Like anyone else's kids, ours can talk for days on end about absolutely nothing. Recently at the dinner table, Justin and Jasmine were carrying on about who-knows-what... My only guess is that it was either science or Minecraft related because all I heard (from the other room) was a lot of talk about gravity. Finally, Naomi chimed in.
Naomi: What's gravity?
Justin: Basically, it's what keeps you from being able to fly.
Naomi: (after about 30 seconds of silence and some serious contemplation) No thanks. I don't want any.
