Homelessness

My brother used to work at a convienient store over night. Every evening there was a man that would go in and buy coffee. My brother is the kind of person that befriends everyone. So he became friends with this guy. It tuned out to be that this guy was a homeless. He was alone. He is very nice and my brother has invited him a couple of times to our house to take a shower and to eat something warm. My brother has tried to help this man out but this man refuses my brothers help. He has never told us why he is homeless and I think that that is something that is too personal and I am sure that he will tell us as soon as he is ready.
