Lately, I've been telling my kids about "yes, and..." and how that's funny.
Tonight, after a long and very drawn-out bedtime procedure, I laid down the law.
"OK guys, time to go to sleep."
"But daddy, we didn't get a bedtime drink."
I'm getting really frustrated at this point.
"Jesus, really?! It's 9:00. Come on.", I blurt out, more profane than I was intending.
