Pat: "Who uses the typewriter?"
Me: "I don't but Lisa does."
Pat: "Why doesn't she use the computer for that?"
Me: "I don't know, ask Lisa." "I think she still has labels that need to be typed on."

...look of confusion

Pat: "So who uses it?"
Me: "Lisa uses it."
Pat: "For what?"
Me: "For labels that she has that need to be typed on."
Pat: "Why not print them?"
Me: "I don't know, ask Lisa."

...another look of confusion

Pat: "It's going to the new building."
Me: "I don't know." "Ask Lyvonne."
Pat: "We don't know where to put it."
Me: "I don't really care." "I don't use it, Lisa does."

...hence look of confusion

...ring of telephone.

I love being saved by the bell.
