Expect them to be rude, violent, and bossy. Expect them to make a mess, do tasks improperly, and sometimes be an overall pain in the butt. Don’t take it personally (or think you’re a bad parent). It’s just how children are made. And it’s your job, as the parent, to teach them how to behave acceptably and control their emotions.
Now *this* lines up with my worldview! We all suck; but we can become better, not only through practice but also through sanctification.
