Dad: What's on?
Boys: Roll Bounce.
Dad: You guys have seen that already!
Oldest: C'mon Dad, watch it with us.
Dad: No, I've got some work to finish up.
Youngest: You haven't spent any time with us daddy.
A beat, then:
When you're children stop asking to spend time with you, or don't ask at all, that's when you're no longer a father!
