When you stay in bed later than usual in the morning.
Example: I'm so tired! At least it's Sunday tomorrow and I can have a lie-in.
When you wake up later than you planned, by mistake.
Example: Oh no, I didn't hear my alarm go off. I'm going to be late for the meeting!
Do you usually have a lie-in on a Sunday? Or do you prefer to get up early and make the most of the day?
Have you ever overslept for something important?
