I dropped DD (7th grade but not 13 until June) at the movies to see Cinderella with a friend. I made sure they hooked up before I drove away.
I was in the parking lot reading when the movie let out but was reading a book. When I looked at the theater, DD was standing there by herself looking at her phone. Her friend had already been picked up as they probably parked at the curb instead of in a spot like me, and they drove away.
I was kind of surprised that they (the parents) didn't make sure my DD was picked up or at least confirmed I was on my way.
Miss-communication happens at this age when young teens are starting to plan going out only with friends.
I would have waited until the friend (even though she had a phone) touched base with her parents before driving away.... or am I too much of a helicopter?
