The triplets have a new rule that they can't say certain "naughty words," and if they're caught saying one, the offender owes a quarter to whomever caught them in the act.
A slice of conversation from yesterday's drive:
Colin: Abby! You owe me a quarter!
Abby: Colin! STOP telling me to give you quarters! Just STOP IT!
Colin: But I heard you... you said...
Abby: You are DEAF! For CRYING OUT LOUD!
I laughed for 20 minutes.
