Beware, this may amuse you.
Someone I know has a habit of leaving their flies open. I always point it out (discretely of course) but often have a good giggle about it. I see people every now and then jaunting around town with the zip low, and I think to myself- how on earth do you not check before you leave the house?
Well. Yesterday, I taught a class for a whole HOUR with my flies open. And they were teenagers. And I had to find a discreet moment to do them up again, which was not at all easy.
CRINGE, CRINGE AND CRINGE AGAIN. BIG MASSIVE CRINGE.
Totally embarrassing teacher moment, and possibly a hit of karma too. Funnily enough, I've actually done this before. You'd think I would have learnt. Well, you know what they say: you can't teach a teacher!
