Jules I have definitely learnt my lesson and now very rarely lend anyone anything unless I'm 100% sure I will get it back. When I was younger I had a video tape of music videos and perfomances by all my favourite bands and it had loads of Glastonbury footage on there, including a clip of Noel Gallagher performing an acoustic performance of Wonderwall before it was released with Liam spoiling it and when I lent it to a friend, her mum bloody taped over it! As a 15 year old who was just discovering music, I was devastated (I'm over it now. Just). Then at college, I lent a cd to a friend (I fancied the pants off him and wanted to impress him) and had to practically rip his head off to get it back! And when I did, the inside booklet was missing! If I borrow anything off anyone I treat it with respect and I can't stand it when you lend people stuff and they let it get mixed up into their own possessions and therefore 'lose' it!
Wow, I didn't realise I was so annoyed by it until I posted this, thanks Jules!
