Truly kind gesture

Yesterday I went to eat alone in B.R while I was there I saw this woman. I'm sure all my LSU readers have encountered her she's bald and has some disablitiy or mental illness. She's never asked me for money, I've never even seen her begging but she's always around and in some trance like stage. Yesterday, she was having lunch with this middle aged well-dressed white woman. The woman [white lady] didn't seem to want attention, there was no camera crew, she was just doing something kind. I was touched. It's so rare to see a truly kind gesture from someones heart. This woman didn't seem to gain anything from buying this other lady lunch she just did. It makes me wanna do something... asap
