Just Do It

I went to Walmart the other day and saw a man out holding a sign. Whenever I see anyone doing that I always try to help as long as I have cash. I wasn't able to give much but at least I gave. Too many people are judging and when I talk about what I have done I hear "I never do that, they could be scamming you". I say "just do it" because in my mind and my heart I know I did the right thing.
