I think there are two main opinions on this. You either see giving homeless people (vagrants) spare change as a waste as they'll just go and spend it on drink or drugs, or you dig deep and give whatever you can anyway. Personally I can't help myself. If I see a vagrant, I have to give him/her whatever I can spare. One time I gave a homeless guy a tenner just because he asked so politely. I know what it's like to be out, miles from home, hungry, cold and in need. I know the desperation of it all. I try to talk to them sometimes. Make them feel human. To be completely honest, some of the best and most interesting conversations I've ever had have been with vagrants. I actually respect their opinions on reality far more than the ordinary sheeple I encounter. Well, mostly. I've spoken to people that prefer to buy vagrants food instead of giving spare change as you know that they aren't misusing your money that way on booze or alcohol. Anyway, what do you do? It seems most people just ignore them and walk past.
