She'll call me when done

Since there was no parking around, I dropped off Allison at Lelenitas in San Francisco to pick up a Tres Leches dessert that we'd bring to Christmas eve dinner with Temis and Carolina.  Then I drove around the corner and found a place to park to wait for Allison.  I figured she'd call me when done, so I'd come back to pick her up

After about 10 minutes I thought she was taking a long time so I called her.  Then I heard ringing.  Her phone was in the car.
