Who is she?

It happened  on Friday, 23rd April 2010.

In the morning at school, I wanted to go to the toilet. Then my friends, Ayu accompanied me to go to the toilet near X4. There are three rooms, two toilet rooms and one room for storage. When me and Ayu came, two toilets were empty and in a state of open doors, while the storage room was as usual with the door closed. I entered into a toilet, while Ayu was waiting at the exit door. When Ayu turn around, she saw a girl with scout's uniform was standing and walked out from the toilet. Ayu was surprised. How can suddenly there was a girl in the toilet? According to the logic, if the girl was already in the toilet before me and Ayu coming, why did both of the toilet were empty in a state of open doors? Meanwhile, when the girl came after me and Ayu came into the toilet, why Ayu did not see the girl went into the toilet when Ayu was standing in front of the toilet door? Who's that girl? Let it be a mystery.
