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.
In fact, two girls, both named Courtney, expecting helpful strangers.
Personally, I wouldn't have one of my kids picked up by someone who wasn't well known to the child, even if that person was well known to me. Especially at age 6 or 9. Actually, there are few people I would have pick up a child that age for me, even of people I know. But that's just me. There are lots of parents who do.
