Aw, that's sad!
When I lived in England I had an old wonky camera that was tricky to load with film -- the only way to know for certain if it worked was to hear a certain sound (a click?) which obviously didn't work for me. I'd gotten pretty good at figuring it out though.
I took one solo trip to Kew Gardens, and took a roll of the most amazing photos. I was really excited about them. Once I'd "used up" the roll (yes, you see what's coming), I opened up the back to take it out and found it had never loaded correctly. (The counter advanced each time you pressed the button, whether the film was loaded correctly or not.) Sigh. I have some of 'em seared in my mind's eye, but that's it.
I know I've had things actually stolen but I'm not coming up with anything. Main thing coming to mind is the fact that a friend of mine made sure our house was protected in our bad-and-getting-worse neighborhood in high school. My dad had a false sense of security and kept getting bikes stolen after I left (and the protection was lifted). (I didn't know about the protection until after the fact.)
Sorry about your rings, Linkat!
