The End of the Booster Seats

Overheard in the minivan...
Blond Twin:  "Hey!  Mom! Didn't you say that we'd be out of booster seats when we turned eight?"
Mom starts laughing.
Blond Twin:  "We don't need to be in booster seats?"
Mom:  "Nope."
Blond Twin:  "Why are we still in booster seats?"
Mom:  "I was waiting for one of you to remember that you could get out now that you are eight."
Blond Twin:  "Let's get them out of the van today."
Mom:  "Okay.  Remind Daddy when we get home."
Blond Twin:  "Oh yeah.  It will be the first thing I tell him."
