So, I was reading through the strange things found in teenagers bedrooms thread and I was reminded of the weird things that I find evidence of when my teens have had friends round. For example: Some time last year I'd been shopping and bought some new underwear. I went out that night leaving the underwear and some other things - still with labels on - on my bed. When I got back the next day everything was still there except the underwear.....it was never found. Someone stole my underwear. Not the clothes. Not food. Not valuables. The underwear. It wasn't even especially 'fancy' underwear just run of the mill H & M stuff, in a colour so unpopular it was on sale...
