so i went up to library and fell asleep and woke up with 3 minutes left in the next period. Think it may work?
My Mum would never believe that. She’s a smart lady though, and I’m not a very good liar, although I certainly thought I was when I was a teenager.
I would just tell her that you were too tired because you stayed up to late, it’s partly her fault anyway. Especially considering the fact that you had to go to work, I’d want to go to sleep too.
