Scene: Son leaps out of parked car and runs out to Dad without checking for traffic
Mom: What are you doing! You need to look both ways before you get killed!
Son: (immediately goes into guilty, self-flagellation mode) I KNOW! I'm just DUMB!
What Dad *should* have said: You're not dumb, you just need to keep your head on straight and be careful even when you're excited.
What Father-of-the-Year actually said: You're not dumb, you're just stupid. (Pause) Sometimes. (Awkward Pause) Like when you don't... think. ( More awkward pause) But I still love you!
