Neither do I - at least not here, but then it's a story that I've told several times. Among the first things which go is "to whom did I tell this and to whom not". That level of accounting becomes completely unreliable - and, frankly, I could keep it up up to my mid-thirties or so. I just gave up and started checking. The larger trouble is how to check without blurting out a spoiler :).

She and a friend finished before time and asked if they could leave. Now I wasn't supposed to give any feedback but we were on a friendly basis. I settled for "you may, of course, but if I were you I'd use the time to check my papers". They both did and later thankfully informed me that they'd spotted umpteen errors besides those I'd spotted.

We all need Auntie Emma from time to time.
