Remembering this random conversation between then-13-year-old daughter and me still makes me laugh...
Daughter (upon coming downstairs in the morning): Ah, it's nice to see everyone is finally up.
Mother (grinning): Says the last one up.
Daughter: Oh, I've been up for a while, but I stayed in bed to read.
Mother: Well, that doesn't count then, because you're the last one down.
Daughter: Oh, I was down earlier to use the bathroon, so I was up before you and Dad.
Mother: But you went back up, so that still doesn't count.
Daughter: Yes, it does ~ I was up, then down, then up, then down.
Mother: But since you're the last one down now, you're still the last one up!
This kind of verbal volleyball is a regular occurrence in our family. I guess it keeps up mentally sharp (or possibly confused). Do you think we'd make good trial lawyers? :-)
