Awww that is really sad. I do feel for guys as it can lead to some awkward situations. Not that long ago a load of us went iceskating and were round at different speeds and in different groups, up and down watching, getting a drink etc... One of the guys was skating round on his own at one point and was approached by some very arsey women who started interrogating him about why he was there on his own as a man, was he a paedophile etc...
I feel awkward enough sometimes keeping an eye on very young children I see on their own around town, a very busy city centre, unfortunately quite a few too, to make sure they are with someone, keep an eye on them and help them if needs be.
I worry, maybe unnecesarily, that people will think I'm some potential child snatcher and I'm a young(ish) female so must be far worse for men. It wouldn't stop me helping a child if they needed it though and I've reunited a few who had got separated from their parents. At least shops are easier as you can entrust them to a security guard or assistant who can do a tannoy call or similar.
