You are struggling to make small talk with someone and suddenly blurt out "You'll have to forgive me, my words have stopped working."
You stare at a counter top with a teapot and kettle on it for up to a minute, trying to remember what these things do and in what order you are supposed to use them.
You walk through the house picking up things that need your attention, then find yourself in the kitchen holding a sock, a free newspaper, a hair bobble, a phone charger and a jar of Sudocrem, then sit at the kitchen table for a bit because you can't work out why you are holding them and what they might do when you put them all together.
21 hours sleep since Monday, how about you?
