At 12, yes, my daughter's did that sort of thing. As they got older they thought it really hysterical to moon me occasionally. My easy child, 19, suprised me one day while horsing around and gave me a light slap on the b.u.t.t!! I said, "uh, no honey - don't do that, it's disrespectful even if you are just kidding around". She got it.
I don't think that kt meant anything provacative by it, but if it made ANYONE feel uncomfortable then it's simply not okay. With the history she and wm experienced, I can totally see that your radar is always on HIGH for that type of behavior.
I think it was good that you called her on it, but I wouldn't make a BIG deal out of it, just keep an eye on it, especially if she was doing so well in every other area.
