I think I remember you being 17 or 18 (I'm too lazy to look at your profile). When I was your age, I thought my parents didn't have a clue about life, especially a teenager's. What could they know, they were so OLD (late 30s, early 40s, which ask Sapper, Ron or Mr Jack, it ain't old). By the time I was 21, it was amazing what they had learned in those few short years.
Remember this if you remember nothing else. They give you rules, directions, instructions, etc, not because they are wanting to limit your fun, "just because" or because they want to be difficult. They do because they love you and don't want you making obvious mistakes, often times the very ones they may have made themselves.
You learn from the mistakes of others and so as not to make the same ones they made-you can't make all of them by yourself.
One of the greatest fears that I have is that my daughters will travel down some of the same roads I did.
I'll quit preaching before I get to meddling.
