Dealing with teenagers, a no cope zone for old Granny

I really don't like the whole business of handling teenagers. They "know" so much to have so little experience. But I figured this problem out.... yep the magic words... "Call you mother about that!" Thank you Lord for cell phones. A few calls to Mom while she's paddling a canoe down the creek did the trick.
Now I know all of y'all notice I found a picture of a skinny young girl... well I had to make myself feel better and putting a pudgy old woman up would not help my mood.
