I used to lend friends my pinions. I knew which were mine as I used to write on them in a red artists opaque pen.
One day I wondered where all my pinions had gone...no one owned up, so I asked to borrow a pinion off someone else, and guess what?
the pinion I 'borrowed' was one of mine anyway!!
But what p's me off is that when I asked if they'd got any, no one owned up.
