Marilyn's Fingers Do the Walking for JoeJack

Marilyn spent at least an hour on the telephone this morning calling dentists for JoeJack getting pricing for three extractions and appointment availability. She would call JoeJack to give him the information after each call then ask if that particular dentist was OK.

He finally agreed to one so SHE called the dentist back to make the appointment for 2:00 today. She then announced that she's leaving at 12:30. This leaves us wondering....

Why can't JoeJack call the dentist to get the information?

After he agrees to one of them, why can't he call back to make the appointment?

Why does she have to leave at 12:30 when his appointment is at 2:00? Oh, wait, we think we may know that answer to that one. She probably has to go ease his pre-dental appointment jitters.... if you know what we mean.....
