Eldest Son is now at a point in his life where we can't really tell him what to do. He's 19, out of the house and legally an adult. And, as people at this point in their lives are wont to do, he is making some foolish choices. These foolish choices may or may not end badly; that's the problem with foolish choices. However, Dear Husband and I had to have a chat with him this weekend and say, "We can't tell you what to do, but we can tell you that we think you're making a mistake. AND (here's the biggie), we don't have to support you. That's means you're not getting any more money from us. Your cell phone is cut off, and you're on your own. We can't tell you what to do, but we don't have to subsidize stupidity." Big boy choices = big boy responsibilities.
Of course, he's fine with this, because he doesn't see anything wrong with the choices he's making. Since both Dear Husband and I have been 19, we have the experience and knowledge to back up our tough decision. Eldest Son thinks he's all growed up, and we know he's not. It's one of the tough things about being a parent. Tough or not, it's what parents have to do.
