Going back to the OP, this is interesting. It was my birthday today. It was a lovely sunny day in Durham, which if you've never been there, has a pretty small, compact city centre. I went into the city centre to visit a couple of shops (hoping to spend birthday money) and then have a drink and watch the football. As I walked through the centre of town, literally dozens of people seemed to know it was my birthday, and I was stopped every few yards by someone wanting to wish me well, in some cases people I barely knew. Later, I went to the pub for a few drinks, a couple of really quite lovely girls who are friends of mine, but who I hadn't specifically asked to come out, appeared, and spent the evening draping themselves over me, making me look actually borderline cool to any casual observer. Funny how stuff goes.
