practically on purpose

I do a bathroom run with 9 kids
come back
and Number-One says
"I accidentally peed in my pants. It was an accident. I didn't know I had to go when you asked. I have a change of clothes"

I feel a little bad, but really. I had asked 3 minutes before if anyone had to gooo

and she didnnnn't

and I had to deaallll withhh itttttt

and she's 6. Definitely potty-trained.
