Note to self: Find instruction manual for mobile

I'm at home right now due to the fact that our morning classes are on holiday, and Young Secretary has just rung me on my mobile. She informed me that New Girl was ill and Bossman had told her to call me to see if I would fill in. She wanted me to teach NG's 13h45 - 15h15 class as well as her 19h10 - 20h40 class after my 17h30 - 19h class. I really didn't want to teach either, as I'm using the extra time to catch up on correcting essays and exams, but after a bit of convincing I told her I'd take the earlier class. They can't possibly expect me to take everyone's classes when they're ill.

I really have got to learn how to use the 'call screening' feature on my mobile.
