| 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. |
