Yelling and screaming tires you out fast. So does continued emotional upheaval. Once you’re tired from either, you usually don’t even have the gas to run away any more.
If you’re holding down someone who’s going crazy trying to get out of your hold or going crazy trying to get up, if you really want to shake them up, as soon as they start to tire, whisper to them “Oh, you’re tired now?”
They’ll usually go nuts for twenty seconds in a last gasp. Then they’ll give up from exhaustion.
At least that’s been my experience.
There’s been some loud crazy guys who scared me. But it’s usually the quiet ones who watch from a well chosen seat that gave me the chills.
