I'm very glad you did what you did. My mum fell over and broke her arm in Cambridge. One guy stopped to help her up and then wandered off. So a lady of nearly 70 was left standing in the street with a badly broken arm and no assistance. In the end she continued her walk to her GP, where she had a routine appointment, and they helped her. But I was shocked that nobody helped her in the street - not even to call 999.

On the other hand, I did pass a bloke lying on the pavement on the road which leads into town from our house. However, he looked perfectly happy - he was smoking a fag. Why his trousers were around his ankles, I did not enquire. But I made the decision that he was conscious, not asking for help, not in distress, and not being a particular nuisance, so I left him alone. Right or wrong? Still not sure.
