Plane departure?

So we had a pretty interesting flight out. We boarded the plane, only to "de-plane" (is that the proper term?) a half hour later. They did end up getting all of us on a new flight, but a bit of chaos. Not a big deal, but people were exhausted before we even left Portland. Especially when you want to be somewhere. And especially when two of your three kids are wrestling in inappropriate places before we have even left the gate. Guess which two?
