Sari (4) and Ada (2) went down the hall to visit Penina. Apparently she wasn't home because no one answered their knocks. Sari came back to the door and was holding it open, urging Ada to come back home while Ada was stubbornly holding her ground. After a moment or two of this, Sari called out:
Mom, I need some assistance.
Me (surprised to hear her use that word): Assistance, eh? Where did you hear that? Who says that?
Sari (with a mischievous twinkle in her eye): Daddy says that to you.
Me: He does? When?
Sari: When I'm not going to bed!
