Don't say...it's late.
We've just got home from a thing we went to tonight.
Can you see the time ?
I am so tired. Lisa just reminded me that on a normal night at home I am already well and truly asleep.
I used to be in that habit of counting the hours of sleep I'd get from the time I went to bed and then I'd weigh up if I would be tired the next day. I don't do that much anymore...why would I ? I'm normally in bed asleep by 9pm !
