Hi,
On the subject of lost and stolen things, about 15 years ago I found a wallet with about £300 in it. It also had some credit cards, and some personal items in it. I returned it to the owner, and they didn't even thank me for returning it.
About a couple of years later, I found a discount rail card. It had the holders address on it, so i wrote a note, stuck the card and note in an envelope and posted it back to the guy. I got a very nice letter back from him, thanking me for returning his rail card. He did not expect anyone would go to the trouble of returning it.
Times have changed though. I had my wallet stolen whilst I was working on my car. I left the wallet on the car whilst I was underneath it (under the car). when I finished, I noticed my wallet was missing. I assume it was taken by one of my neighbours, since it is a private road, which leads only to the back of the houses on the row. No-one else really comes down the road. The wallet only had about £5 in it, but it also had some photos and other personal items in it.
It makes me 'uncomfortable' to think that one of my neighbours (or one of their visitors) came and took my wallet whilst I was right underneath the car.
Now I don't trust anyone.
