I find this quite amazing, actually. When we had our very quick tour through London (I really love London.) One of the kids left a shopping bag with a few souvenirs we had purchased in the London bus we were travelling in. When we realised we had lost the bag, it was about five hours after we had been on the bus. I really thought we had lost the bag and thought someone would have taken it, but everyone else thought it was worth contacting the bus company.
It turned out that someone had taken the bag, and had handed it in! The South Africans will understand when I say that this would probably not happen here. Anyway, the bag was sent to us, and I have it now. Totally unbelievable, but true.
