We had a very warm day today so I got to do a little yardwork after school. The kids helped and enjoyed riding their bikes.   I was busy weeding and putting rock borders down for my back flowerbeds when I overheard them.

Brother:  "How come you know so much all of a sudden, sis? Huh?"

Sister: "Because I'm six years old, that's why!"

Brother: "Well I'm three years older than you are, whaddya think of that?"

Sister: "Everybody knows you lose your smarts after you're six."

Brother: [uncontrollable belly laughs]

Mom: [turn away, don't look, don't grin, pretend I didn't hear....]
