aperitif, anyone?

Last night I got home and my housemate offered me an aperitif.
Splendid. Lovely pre-dinner drinkies. Just the thing.
Upon relating this occurence to my office mate it became apparent that each of us needs to listen a little more closely to the other (and makes me wonder how many other conversations we’ve had resulting in similar confusion due to poor diction.)
I told Trish that Justine had asked me if I’d like an aperitif. To which I’d responded, “Oooh, yes. Lovely.”
Trish looked at me strangely. “She offered you a pair of teeth?”
“Yes,” said I. “We don’t have them very often. But she had a craving for one.”
“Right,” says Trish. “A pair of teeth. She craved a pair of teeth.”
“Yes, indeed,” said I. “And it was delicious.”
Trish looks confused.
“What?” I asked.
Trish laughs.
I laugh.
Trish: “It wasn’t ‘a pair of teeth’, was it?”
Me: “No.”
Trish: “Just checking.”
Both: loud, extended laughter!!
