What do you mean you only got 2 hours sleep last night? You had to go to work in the middle of the night? Then when you got home you started to tidy up some stuff and made a real mess. Then the exhaustion struck so you climbed into bed at midday for a snooze. You had just closed your eyes when you got woken up, as your sweet niece was passing by and bought you a parcel of stuff.
So now you is awake and have to clean up the mess you made and be back on call tonight. Good job mum. You should be a cat - much easier!!
