On my home planet, no one can see you if you hold your hand in front of your face. So if for instance you're in an argument with somebody and you want to disappear, you just hold your hand in front of your face and suddenly they can't see you. So you keep holding your hand in front of your face and walk away and nobody can tell where you went or what happened.

It was a little embarrassing to learn it doesn't work like that on your planet.
