On the Greyhound coming down from Montreal, I sat next to a window with an emergency exit. The little message read:

EMERGENCY EXIT
LIFT this bar, PUSH window OPEN

But what bar? If you looked, there was a lever a couple of inches to the right of the little message. But that’s not a bar, and I would think you pulled it up instead of pushing it.

This kind of thing used to drive me crazy when I was a kid.
