This small trick will work when your
friend has drifted off to sleep, say, on the bus, in the classroom or at
work.Shake his/her hand violently, waking him/her up, and ask, "Sleeping?"
He/she will say something like "Yeah..."
And you end by saying something like "Okay"
or "Oh."
Do it a couple of times more for effective nurturing of irritation!
Sounds simple but works great!
