you.are.right.

mama:  SO, what was your favorite part about being at grandma's?
xander:  Watching Franklin.
libby:  going for a walk with em.  And we were really glad Xander and Phoebe didn't come with us.  You'll understand, mom.  It was a REALLY hot day, and Em and I were so glad Xander and Phoebe didn't come because they would have really slowed us down.  And made us more hot.  Phoebe would have needed Em to carry her, and that would have made her more hot, and Xander walks really slow when he's hot.  And we had to be home in 30 minutes.  And we were 10 minutes early.  But they would have really slowed us down.
xander:  Libby, you.  are.  right.  I WOULD have slowed you down.
