Ive lost my wallet once, it was on my birthday too. I lost my card, a few quid and all my cinema reciepts I was gutted.

I left my DS case on the plane to Tenerife. Luckily, my DS wasn't in it, but 2 of my brothers DS games were (Pokemon Diamond and Nintendogs) and all of my older Advance games were. My brother went mad, I have to buy them again ;;
