Bummed today

My girls and I see this old homeless man almost everyday. He nevers asks anyone for money, and always seems to take care of himself and his responsibilities. The only time he seems to spend money is on food or doing his laundry. He seems very nice, and keeps to himself. The last couple of weeks we have noticed that his only jacket is torn. Not just ripped, but it looks as if someone literally shredded it to pieces. He still carries it with him and wears it when it is cold. Lately it has been cold often. My girls got the idea to save their money and buy him a new one. So yesterday they bought one. We drove around until we found him and walked up to give it to him while he was shopping for food. He refused it. He wouldn't even listen to us, hear what we had to say, or even look at what it was that we were trying to give him. I got the impression that he was embarrassed. We left the store and left the jacket on top of his stuff outside. When he came out he moved the jacket. He then moved it around several times, picking it up and laying it down. Ultimately, he still left the jacket there and walked away, looking back at it many times. You could tell he wanted to take it, but it was as if his pride just wouldn't let him. We were hurt and disappointed, but I am not sure exactly why. We just walked away confused. We still have the jacket, and have considered trying to give it to him again on another day. After all it was bought only for him. A man who appears to need more help than others, but accepts less help than most.
