Rofl, I am on my 2nd teenager and there is NO ONE SO STUPID as the parent of a 15-year-old. Yes, the same parent who was the smartest person in the world, a wise trusted advisor, just three years ago, suddenly now knows absolutely nothing. Lol. This too shall pass. By 18 or 19, suddenly you’re not that dumb after all. Amazing how Gd takes your intelligence away for 5 or 6 years, then brings it back.
I think it has to do with hormones...:)
It was a wonderful day when I heard my high school junior tell her friend, "Do NOT argue with my mom--she KNOWS what she's talking about!!!"
