So yesterday i made a quick trip to WM for some diaper rash cream. I have to buy several different kinds to keep switching around on her. So went and pick it out went up to the register and she rang it all up and i'm digging around in my purse to realize that I had left my wallet at the house, well was telling her that i was sorry but i would have to go back home and get my wallet and then come back when a lady behind me asked if she could pay for it. I was completely taken aback. I said that appreciated...
