what is the nicest thing you've ever done to someone?

I gave a homeless man a bunch of clothes. I have always had a soft spot in my heart for homeless and it made me feel good to be able to give him something that would help him out. and he was so appreciative of it. he would come visit me alot and sit on the porch and talk with me.. he had a really hard life, he seen someone kill his wife and just a whole bunch of stuff.. so making him have a smile on his face after all that he had been through made me feel good.
