The Terrible Twos Versus The Sinister Sixes

(My sister, her husband, and their baby are visiting. My six-year-old son is whining loudly about not being permitted to show them a funny video and being a little obnoxious.)

Me: “Don’t worry, I’m sure your baby will never be a six-year-old.”

(I immediately realize what I said.)

Me: “No! That’s not what I meant. I mean…”

Sister: “I know.” *laughing* “[Husband], my sister just threatened our baby!”
