Awww this is making me feel all warm & fuzzy ~ and restoring my faith in human nature :o)
I suppose I have done quite a few nice things to help my fellow human..however the only one springing to mind right now is the one when I found 4 bags of Christmas shopping in a store. The bags were huge and they were packed with two Playstation 2 consoles, games, clothes, toys, you name it! I picked them up and took them to a security guard who put them in his office. The guard took my details, and told me he would let me know how it turned out.
I got a call the next day from the woman who had lost her bags ~ she was a single mum who worked two jobs in order to provide her three kiddies with christmas pressies..she had been distracted by her crying toddler & gone off to the loo leaving her bags behind (hey, I have done the same thing!) she went on to say that she was so glad it had been me who found her bags, and that most other people would probably have walked off with them. She sent me a bunch of flowers, which was lovely but unecessary..I just did what I would have wanted anyone else to do!
