Well I Never!

Professor David Spiegelhalter of Cambridge University wants to know about your coincidences!

Down and up

I'd been having a lot of trouble with my boss at work. One morning I arrived to find that a diamond had gone missing from a ring - I was devastated. That same day, however my boss was let go. One loss was worth the second!

Hole in one, twice.

I play regularly on a small country golf course on the Coromandel in New Zealand. On a regular golfing Saturday, about two years ago I stood up on the 7th, a short par three and in front of my three playing partners I hit the ball straight in the hole for my first ever "hole in one". The following Saturday on the same hole, with three new playing partners and with a certain amount of banter, "show us how you did it Al etc" I took my stance, and talked them through it. "Hold your mouth like this, more wrist cock but most importantly think happy thoughts", I swung at the ball and bugger me it flew like and eagle and again dropped straight in the hole. I found some stats some where to suggest it was in the order of 60 million : one. I also note that every time I now play the hole I am somewhat disappointed if I miss! Regards Alastair Sims

Probably being saved from serious car accident

I had a Volvo V50. Although it's by far the most common volvo model in my country, you don't see one very often. I owned it for 3 years and always took great care of it. However, few month prior to selling it, I did not pay much attention to the maintenance anymore. One day a weird sound started coming from the front right wheel. I was somewhat busy at the time so I did not pay attention to it thinking that I simply care too much about everything all the time. I thought the tire did it, it happens. Few days later, I was sitting at McDonald's next to the motorway when I got a strange call. It was my mechanic, who had never called me before, saying that my car is ready after service. He was also saying something about wheels but I can't remember what it was. I was quite surprised and told him that my car is next to me on a parking lot. It turned out the he had another customer with the same surname, model and engine type. I am curious what color his car was, but I forgot to ask and considered it just a funny coincidence. Another few days later, the sound got much worse but I just kept going. I live in a small town and was going to the store.

Thoughts into Actions

I coach gymnastics and we had a competition coming up that weekend. it was in a city that started with an “A”. There were two cities that i kept getting mixed up thinking it was in one then the other and i had to keep checking where it was. I thought “what if i go to the wrong place and the right one is a half hour away.” the night before i look up the location to make sure it’s all set. the next morning i confidently put it in the GPS and go. when i get there it was the wrong place and i put in the wrong town. when i put in the right town the GPS said “28 minutes”.... it was so weird how i had this thought and it came true... not the first time this has happened

Barcelona market

My son bumped into my sister in law in a market in Barcelona (and they recognised each other!). Neither had any idea the other was visiting.

Hugh Hefner

For a couple of months now, i have been watching the hit TV show, Sex and the City. The shows has six seasons and i was currently in the middle of season 3 (season 3 episode 14 to be exact) when Hugh Hefner made a cameo appearance in the episode, as this particular episode was set at a party at the Playoby mansion. This is the only episode of all 6 seasons where Hugh Hefner makes an appearance and literally while i was watching this episode, i receive a notification from People Magazine that Hugh Hefner had died that very day. I have no idea what to make of this other than a very scary coincidence.

A Coincidence Found Out About 20 Years Later

When I was 8 or 9 (I'm 35 now) my dad had a co-worker with a name I somehow remember to this day... It wasn't that unique, but not "Jones" or "Smith".. we'll call him Bob Peppertable.. Although Bob probably played an insignificant role in my dad's life, I remember him as being one of the 20 or 30 people that you know when you're 7... Bob died when I was maybe 12. I remember my dad going to the funeral. Fast forward to middle school in a different town, a few hundred miles and two states) apart. I had a friend name Jason peppertable. For whatever reason, I never put the two together. I remember Jason because he was kind of a bad kid.. Didn't seem to care about the consequences of getting in trouble. Anyway.. Jason was just someone I knew for a year and two and wandered off. Now, fast forward tot he present day.. With google. For some reason it clicked that both Bob and Jason shared the same last name. I plugged in "bob peppertable" and located his grave and family tree on findagrave.com..

My complete Name

I was feeling real bad because I had lied to my girlfriend about a place I was going. So I was having a hard time sleeping. I kept waking up so I got my phone a started reading. I was reading a Quora Digest article online about the 10 ten guitarist. The #10 Lenny Breau I had never heard off so I looked him up on ITunes. He has over 20 albums so picked one at random. In the song titles was my full name but the kicker was the the song titled it's a sin to lie. Lenny Breau- Boy wonder 1. I'll see you in my dreams 2. Cannon ball rag 3. John Henry 4. It's a sin tell a lie Etc etc My name is John Henry Cannon and my girlfriend calls me Cannon ball. By the way I have been having a high rate of coincidences happing at this time

Came Across and Old Friend in a Different County

Since I left Gavilan View Middle School, I had never seen Fabian Hernandez. We were close friends but because we attended different high schools we drifted apart. We are both from Mexican parents, but had not traveled to Mexico. Years later, after I marry, we visit one of my wife’s uncles in Mexico City. I love going to theme parks, so we decided to go to Six Flags Mexico. When we were waiting in line for a ride, Fabian, who was also waiting in line, recognized me. He was visiting his wife family in Mexico City as well. After talking for a while, it turns out we live just a couple of blocks away in Salinas, CA, yet we came across in a different country. What are the odds?!

unintentional stalker

I went to a printing workshop in a local independently run class in Sheffield UK. There were 10 people in the class. I got chatting to the woman opposite me. She was Austrian and it turned out she was a good friend of my cousin who is also Austrian and lived in Vienna. She also had a studio in the arts centre where I worked and when she gave me her business card I saw that she also lived in the same house I lived in 20 years previously. We were both more than a little incredulous and suspicious, both believing the other to be making it up.
