Sophie threw her first full-scale temper tantrum as a first grader today, with the requisite tears and screaming, shutting herself in her room, threatening not to come down to dinner unless we met her terms, screaming “I’M SORRY!” in her angriest voice, and other general unpleasantness.

When she finally calmed down, I sent her upstairs to get ready for bed. And she skipped up the stairs singing, to the tune of “If You’re Happy and You Know It”:

If you’re angry and you know it, throw a tantrum.
If you’re angry and you know it, throw a tantrum.
