Waking Up

I woke up this morning to my phone ringing.

Melissa:  Hello?
Becky:  Did I wake you up?
Melissa:  Uh....
Becky:  I just wanted to let you know that Preston is calling people on Bill's phone.  He's called us twice this morning to invite us to a surprise party for his animals.
Melissa:  Bill, quick!  Get your phone away from Preston!
Bill:  Give me that!
Carter:  Daddy, how did you know we were using your phone?

Later....

Melissa:  Preston, what did you say on the phone?
Preston:  Uncle Matthew said, "Are you supposed to be using your daddy's phone?" and I said, "Bye!"
