humm...good question...I'd have to say that the most selfless thing I can remember doing is when I gave this random guy that walked up to me in Wal-Mart and asked if I could spare a dollar for his baby's juice box. The guy came back to me later and tried to give me five dollars back and his thanks and I told him to keep the money and I just took his thanks. I felt really good after doing it but I don't think I'd do it on a normal basis because some people would take advantage of me...but this guy seemed desperate to me...and it paid off! It was such a cute baby!!!
