Meeting at Dinner

Whilst at a week long statistical short course run at Bristol university there was an evening meal. Around about 30 people went to the meal and I sat done to one person I knew and another I had never met or talked to before. Eventually I started talking to this girl next to me who I did not know, and she asked me where I was from. I replied "the Reading area" which she obviously knew so I said "well a small village near by called Finchamsptead". She not only came from the same village as me (population around 12500) but also went to the same primary school as me (about 400 children). We were three years apart so were even at the same primary school at the same time!
