I only lend my Lowden or Martin to people whom I choose, not those who choose me. Usually works fine. However, I once took my Lowden to a new (to me) session at a pub, went to the bar for a beer and heard someone thrashing a guitar behind me. When I turned around I saw that the guitar was mine and was being held 'upside down' (i.e. left-handed) and hammered very hard by some harpie who had, two minutes earlier, asked (and been politely refused permission) to play it even though she admitted she wouldn't know where to start. A bystander later told me I looked like a frog in a blender as I leapt across the room (no mean feat at 17 stone!) and wrestled the daft bat to the ground in order to recover my guitar before any damage was done to it. She was so thick she didn't see what she'd done wrong, even when I explained it would cost her seventeen hundred quid if she broke it - told me I was a misery! What do you do with them?
