(Note - This is mostly a rant sessioin. Obviously I want to instill a lot more than just these two lessons in my kids.)
1. When you get married, MOVE OUT!
I've noticed a bit of a trend lately with some youngins getting married and then moving in with one of their parents instead of moving out on their own. Observe this passage in scripture:
Genesis 2:24 - For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.
It doesn't get any more clear than that, folks. When you get married, you need to be on your own with your new spouse. I'm sorry if I offend someone out there, but that's how I feel.
The only exception I will make to this is if my kids have found a place to stay and the wedding date happens to be before they can move in. While that could be considered poor planning on their part, I'm not going to be crazy with this rule. But they don't need to get married with the intent of staying with me indefinitely. I'm sorry, but once they have decided to live with someone else, they've decided not to live with me.
The main lesson I'd want to teach here is that when they get married, they need to be ready to build their lives together on their own. And I don't think moving in with their parents and still having some dependence on them is a good way to do that. I'd love for my kids to live close to me when they get married. Just not with me.
2. If you aren't legally allowed to get married without my permission, WAIT!
Along the same lines as that last one - I've seen a couple of people get married before they are 18 and thus ask their parents to sign a paper saying they are allowed to do so. Again, I don't want to offend anyone, but that's just crazy to me.
I don't see any harm in waiting. Maybe that's because I started dating my future wife in high school and we didn't get married until we were 21. I can simply say that we were definitely not ready to get married before we were 18 even though it is obvious we would still be married now.
The main lesson I'd want to teach my kids with this one is that they need to make sure they are really ready to face the world on their own. And I don't think anyone can claim that at 17 years of age or younger in this day and age.
