Most parents when they send their kindergartner to school: Bye, sweetie. I'm going to miss you so much! Have fun and learn a lot!
Me: David, for the love of all that's decent, DON'T throw chairs across the classroom, and for godsakes, please leave your underwear and pants ON.
True story.
As Kurt Vonnegut would say, "Laughter and tears are both responses to frustration and exhaustion. I myself prefer to laugh, since there is less cleaning up to do afterward."
