Are They Really Coincidences ?

My mother never believed in coincidence and often talked about these things that others referred to as coincidence as just normal life but sadly I did not really take much notice until recent years, as I've reached middle age - and thought more about the meaning of life etc. as I suppose one does at this time. Now that I am aware of what I call 'happenings' (as I am firmly in the 'no-coincidence' camp) they occur all the time and I will give a few examples now and then update from time to time if that's ok ? One happening that springs to mind immediately is the fact that whenever I go away on holiday I always meet someone I know, whether it is here in the UK or further afield - recent examples are this in Cornwall I saw on old friend who lives in a nearby village in Looe one morning plus my girlfriend's friend staying across the way from us -- last year I spotted one of my youngest son's teachers on the plane coming back from Tunisia - oh yes and earlier this year on the way to Spain I saw a neighbour at Southend Airport. I live in fairly large town but most days while driving or cycling around I will see the same silver Mercedes car driving around (it has a distinctive number plate so easy to spot) - in a typical week, I will see it 5 days out of 7 and sometimes two or three times in a day. This car does not reside in my immediate area, and I have never seen it parked on a driveway anywhere close to where I live. I have not used a alarm clock since I had a paper round 40 years ago and whatever time I wake up I can guess the time within 10 minutes and on days where I have to wake up at a certain time, I can do that easily without the use of an alarm - probably not what you would call 'coincidence' but still a bit weird ? Getting back to work but will post again with more thoughts
