Neil: Would you like a cup of tea?

Another: I had one earlier.

N: Yes, me too! Would you like one now?

A: It's getting late.

N: So is that a "no, thanks"?

A: Yes.

N: As in "Yes, that's a 'no, thanks'"?

A: Yes.

--- Some minutes pass ---

A: Did you say you were making tea?

N: I did, and you said that you did not want a cup. But no problem, I can sort it.

A: Do you have decaf tea?

N: Yes.

A: In which case, no, thanks.

N: *walks into the sea*
