I used to work with the homeless. I had to stop because nothing really could be done for them, and i couldn't cope with that.
This Gent i sensed wanted his privacy so i kept a respectful distance. Many are this way. Others like to chat and have a laff ... though that depends how they are feeling at that moment.
The Inspire a Generation for me would be to inspire to make some sort of change. One homeless Gent with a doggie said there's only one dog n man shelter in London, other homeless shelters wont accept him as he has a doggie.
