Me: *staring out the window and imagining myself at Hogwarts playing Quidditch*

Teacher: *calls my name*

Me: *looks away from window* HUH?!?!

Teacher: I said what are the M.A.I.N causes of WW1?

Me: Oh...militarism, alliances, imperialism, nationalism

Teacher: Good.

Next Day-

Teacher: Are you feeling okay?

Me: HUH?! Oh, yeah...I'm fine...just great.
