I think it's weird the way I fell asleep on the day before school started.
Why do you think it's weird?
It's something that I don't want to talk about but thank you for your concern.
Sometimes things happen that is difficult to explain. You should talk with someone you trust if you are concerned about what happened.
You are not my therapist, so stop being so nosy. I already said that it is none of your business.
I'm not prying. I'm concerned about you because I care.
