I actually had someone once that was being kind of verbally abusive, and we ended up not taking him. They act sometimes in ways that I don't think they do when they're just out in normal society. Maybe it's being confined, not being in control of what's actually going on. Not having choices as far as food sometimes, not getting to sit where they want. All these stresses add up and just build on people.
People sometimes go berserk over the smallest things.
It's sort of like a relic that they have those airsickness bags on every flight no matter how short the flight is. Almost nobody gets sick anymore, but they use them for a million other things. People take home cookies in them. People warm their baby bottles in them, put their medicine on ice in them. Now I've sort of changed my mind.
