I don't know how to get people to change behavior like this. It's not a huge deal, but I find it really disrespectful that my wife will "clap" her hands our kids when she has certain things to say to them. I don't know, they were doing something wrong. Whatever. But I just find it disrespectful for some reason. And she's also done it at me before. I pretty much left the house when that happened.
Is that something you'd consider disrespectful? Audibly clapping your hands at somebody while you're sing songy chanting something at them?
It's a rare occurrence, but whew.
