What people say when you get too nosy.

Also what people say when you ask for too many details.

None of your concern

Another way of saying “none of your business”

Teacher: I gotta go on a date tomorrow so you’ll have a substitute

Student: Ooh, who are you going on a date with?
Teacher: That’s none of your concern
