Okay, so you know how sometimes you are really good and follow all the rules like listening to your parents and being polite to your friends? That's called good conduct! And when you keep up that good conduct for a long time, you might get a special stripe on your shirt, like a sticker or a patch, to show that you've been doing a great job. It's a way to celebrate when you make good choices and behave nicely. The stripe reminds you and others that you are a good kid who is trying hard to do the right thing.
