Was talking to some friends in the pub last night about this and my most riddiculus argument was when I was at college.
I was on a year long course for work and the other adult students where from all over England and Nirth Wales.
One day I couldn't find my. pen and then I noticed a guy had it.
I asked for it back and he said it was his. I asked him if he was sure about that and he said yes. I replied that it had the name of the community centre that I worked at on. He said it was his. I was getting a bit irate. I pointed out that I live in Halifax ( in the Norh west of England) and he lives in tal y bont nearly 150 miles away and had no connection with my community centre.
At first I thought it was a joke but he was deadly serious.
From that day ( about 10 years ago ) to this I can't work out what went on. We were good college mates. Weird!
