OK, the RevGal Friday Five is about pet peeves. I have a couple.
First, snakes are VENOMOUS not poisonous. Only things YOU eat can be poisonous.
The thing in your car that makes it go is an engine, not a motor. Engines run off chemical energy, motors off electrical energy. Or at least they do in my universe.
I could post about liturgical boo-boos, but really, they don't bother me THAT much.
