Scene: On a deck, Dwee and I sit on deck chairs. The sky blue and clear, I spot a plane, leaving a smoke trail behind it.
I: Oo..an airplane..
Dwee: Oo–I see another one!
Dwee: Do you think they’re gonna intersect?
Dwee: Well, they’re not parallel.
I: They could be skew lines!
[Dwee and I watch the airplanes for a while; they approach each other but keep getting more parallel. I become dejected at not getting to see two airplanes’ paths intersect.]
