Well I never used to, until,
Many many
many moons ago I was a very silly boy, into all sort, anyway to cut a long story short I ended up in hospital, and was kicked out at 3am, 16 miles from home, no money, no phone, just jeans a t-shirt and it was starting to chuck it down cats an dogs style, I wondered the town for an hour freezing my nads off, shivering and tired I eventually took shelter in a shop doorway, I sat down and crossed my arms tightly under my t-shirt to try and gather some warmth, rain still beating down and the air so cold I could see my breath, I sat there scrunched up pondering my predicament.
And then as if by a miracle the next thing I remember is a guy waking me up shoving a fiver down my T-Shirt

, saying
"here mate, go get yourself a warm meal", \O/, I will never EVER forget that guy, the gratitude of some people is amazing, that small amount of money meant soooo much to me at that time, it enabled me to get a bus home and 10 fags, no I wasn't homeless, and I was working full-time but the situation I landed myself in (and yes I realize it was my own fault) made that £5 so important, so now my way of repaying that kind action is by giving the odd fiver to a homeless guy now and again, because if just one time that £5 means as much to that person as it did for me that time then it's worth it.
