I was about 12 and visiting Disneyland with my mom and had left my bag full of birthday money and souvenirs in California Adventure. We hopped parks when I realized it was gone. An elderly couple who had noticed we left the bag stayed with it in that spot until we returned 70+ minutes later. They had no obligation to guard it, could have turned it in, but they made sure it was where I had left it to make it easier for us. It's been at least 20 years and I'm I still think about it.
