Pretty terrifying, but in this case apparently the family friend didn’t know the Courtney he was supposed to pick up very well. Also she had gotten a haircut recently (the right Courtney), adding to the problem.
AND... the wrong Courtney apparently was ALSO supposed to be picked up that day by a family friend who SHE apparently didn’t really know.
So you put it all together and... oops!
Yeah... expecting to get picked up by an unfamiliar person asking for her by name. I guess that explains her mistake, but the fellow...? “Excuse me little girl, it’s my daughter I want to get, not you”
Oh DUH! Two helpful strangers. Two girls expecting helpful strangers.
Silly mix up. If I had a little girl or boy who I wanted a friend to get, I would give the girl or boy the name of the friend on a piece of paper, and tell him or her be sure to ask the friend’s name and check it before getting in.
After getting the further details you provide I'm wondering if there is even more to this story...
