Stupidly forgot to set the alarm last night - woke up at 8.05 in a blind panic about what day it was. Still got everyone out of the door, complete with breakfast, full uniform, football kit, PE kit and packed lunches by 8.25 (was completely out of kilter all day though).
Oh, I did that one Summer day, got half way to work, glad that the traffic was light when I realised it had been 5.05, a water glass had distorted the clock!
