I'm sure you've heard a few
. My most recent experience made my chin drop with its sheer egotistical madness

DS has AS and suffers from Chronic Fatigue Syndrome. Home tutor sessions were often cut short (by him and me) as he became too tired to continue. The sessions were meant to be 1 hour long or 2 hour max, but were often booked for longer due to tutor availability.
Anyway, this said tutor accused me of cutting the sessions short because I wanted to have 1-1 time with her to play cards 
Beat that!
