It's okay.

It’s Monday. The follow up appointment is today and Anna is coming to pick you up.
You head downstairs to check your calendar and you realize the appointment is in an hour and Anna should probably be coming to get you now.
You pick up the phone to call Anna when a car horn honks. When you open the door, Anna and Derek are waiting for you. No Price is Right today.

In the car you ask how she knew the time of the appointment, when you yourself had never told her.
Anna tells you she called the doctor herself after your last conversation Saturday.
In return, Anna asks you about your direction situation with Derek yesterday. You tell her it was no big deal and you both decide not to mention it any longer.

When you pull into the parking lot you can’t decide if you want to

1. Tell Anna about the prescription mix up now.
2. See what happens if/when the doctor brings it up.
