If justin bieber pranked call your house and 你 didnt know it was him just another Person what would 你 do ?

I would ask who it is and 更多 than likly freak out if he 说 his name. If he didn't i would 更多 than likly yell at him like i would any other person 或者 i would go along with it for a little fun.

Talk to justin because I would know it is him.
