So after whining and threatening to cancel the appointment, we negotiated to wake the girls up before they would usually even get up for school so he could pick them up early, take them to the freezing cold beach, and drop them off at the orthodontist at their 12:00 noon appointment time.
The beach is at least one hour from the orthodontist. At 11:30 am, they were still at the beach. He shows up late to the appointment and the girls are wet, shaking and visibly upset. Joc reported: "Dad was cursing and saying bad words in the car..." Well of course he was... that's cause he has road rage.
Ugh... and there's nothing I can do about it.
