The My Gym disaster

"You know, sometimes it takes a couple of weeks. If you'd like to come again next week for free, I'll be working."
The My Gym girl was trying to be nice. She could see I was disappointed. But I wasn't really listening to her.
I was watching Dylan, who was playing nicely but completely independently. He was at the basketball hoop. The ladder. The trampoline.
Close to a dozen other kids and their caretakers were seated in the center of the room, singing songs, doing exercises and having fun at the direction of another My Gym instructor.
"Circle time yucky!" Dylan had said when it was time to sit down together.
So he didn't sit down. He didn't even seem to notice that an organized activity was taking place. He just kept doing his own thing.
"Oh, we don't need to come next week," I told the girl. "It's like this everywhere we go." Don't you know about us? It's a small town. We're the ones who can't even go back to the library....
I followed a few steps behind Dylan as he played. I tried not to hover or pressure him to join the group. He passed behind me, and I turned around slowly. And then he was gone.
Gone! In a room of at least 24 other people, he had vanished.
I called his name. No answer. The other adults were watching their own children. No one even looked my way.
The entrance to the gym was gated, so it was more likely he headed to the back. I called his name near the bathrooms, in offices, down a hallway. A woman changing a diaper ignored me. I went back the gym and didn't see him. I again went to the back of the room and the diaper-changer said, "I think he went in there."
"There" was a single-stall bathroom with a full, heavy wooden door. It was locked.
"Mama, I want out!"
Whew.
"Dylan, you need to turn the button on the handle."
"Mama, I can't."
The nice My Gym worker couldn't open the door, either. She had no key.
That's when the fire alarm started blaring. Strobes flashed all over the building.
"He pulled the emergency cord near the toilet," the girl said. So that's what happens when you pull that thing.
"It's loud, Mama!"
The My Gym girl and I opened every cabinet, looked in every closet, searched every desk, looking for a key or screw driver or sledgehammer. She called the franchise owner and the fire department.
No help came.
After about 10 minutes, Dylan understood how to turn off the alarm. Once it was quiet, we talked him through how to unlock the door. The whole thing lasted about 20 minutes. Once free, he ran straight into the gym and wanted to ride the zip line.
But he didn't get to. Class was over. As we were leaving, I heard the nice My Gym girl giving the sales pitch to another mother who had been there for the first time.
No one tried to get us to join.
I wonder what would happen if we took her up on her offer to come back, just one more time, for free?
