A: Let's play a game. I'll describe someone and you try and guess who it is.
B: ok. I'm really bored at the moment. You describe someone we both know.
B: Yes. She's not very tall and she has curly hair, but I don't know what color her eyes are.
A: Is she lovely? I don't think I know anyone like that.
B: Of course, and she is quite good at math.
A:Oh, is she our classmates?
B:Yes!
A:Ah, it's Alice!
B:You are right!
