USB512 where are you?

I realised that I lost my USB 512MB thumbdrive couple of days ago... Not sure when it happened but I thought it might be on last Friday. My keychain somehow loosened up and my car key dropped out. But I didn't realise whether the USB drive was still there... (yes, I carry it everywhere as a keychain).

Sad sad sad... Now I can't copy my photos from home to school... :(
