Am I the only one who would rather stay at home and watch TV than go out with friends. A work colleague is having a leaving do tonight and I was going to go for the meal part, and then come home when they all move on for drinks. But I think subconsciously I have been waiting for an excuse...last night I was awake for 4 hours so have text this morning with that as an excuse. She was quite short in her reply, so she's clearly narked a bit. I'm such a hermit.....haha
