B: Say that you and I went to a concert together...
Me: That has never occurred in the entire time we have known each other.
B: And it won't.
B: But say that we did, and I was behind you wearing an Atari shirt...
Me: Now THAT could happen.
B: Anyway, you came up to me because you were trying to find your seat.
Me: Wait. What? Who are you in this scenario?
B: Oh, I am playing both parts. I am the boyfriend and the usher.
Me: Oh. Right. That is not at all confusing.
