The nicest thing a random stranger did for???

The best experience I can remember is working at a bag shop. Some customers would be super nice and give me advice, suggest new books to read, etc. One woman came in and noticed a wolf shirt that I was wearing. We started talking about wolves and environmental groups. She told me that she had a ton of free gifts from the various groups that she donated too and said she'd bring me back a wolf tote bag the next day. And she did! I had never met her before, or since, and she had no reason to come back on a separate trips to the store just to bring a stranger a free bag, but she did. I was very grateful because I really do love wolves. It was a nice experience.

So far, there's none. But how I wish I can also experienced what you have been experienced because it was so sweet and cool. Sometimes I am afraid of strangers so I kept a distance from them, maybe that's why I never experience such a thing.
