Brit grad student interaction: blah blah blah, I think he finally sort of got me back?
Him: So what does a plane do when it's close to the ground?
Him: No think about it! What's it doing?
Him; No, no! Really, it's close to the gruond, just there...
B: I don't get it.
Me: Me neither.
Him: There's a plane, close to the ground, what's it doing?"
Him: Yes! How?
Him: YES! Flying low! Goodbye!
I was mildly embarrassed, but I laughed and yelled at him. I've been sniggering about the whole thing since.
