It's true, my sense of humor is sarcastic. And I do use it on the kids sometimes (or Abby would not have known about rhetorical questions at seven). And it's also true that Leanna (11) and Abby (nearly 9) are both at awkward stages where they don't seem able to keep track of their body parts and are constantly hurting themselves or each other or other kids or adults or toys, inadvertently. So far the holiday we've had half a dozen stubbed toes, a poke in the eye, and a number of spilled plates/bowls/glasses.
So today, when Leanna leaned forward to get out of the rocker-recliner and I heard a crunching sound, I made the snarky remark that if she just watched where she put her body parts, we'd be able to keep things longer (it was a plastic slinky and is just fine by the way - they have give). Leanna (being an adolescent) took this as a personal affront and the door to their bedroom was closed rather more forcefully than I'm comfortable with. However, since there were no shrieks of pain or outrage associated with this door-slamming, I let it go this time. She recovered pretty quickly too. Usually she's inclined to be mad for a while, because she's stubborn and adolescent and eleven. But right now the four of them - Leanna, Abby, Lizzy, and Kiki - are playing Hide and Seek and having a ball.
So I guess my sarcasm isn't going to do them any permanent damage.
