Is there a little humor?

There was a girl who loved to fart since she was a child, so her father cut a fart plug for her with wood. One day, she went to the toilet on the school playground and took off the fart plug and hung it on the wall. It happened that a PE teacher came to the toilet and hung his whistle on the wall. They took the wrong things when they left.

The girl was walking in the street trying to fart. She can let go if she wants. No one can hear her anyway. Then ~ ~ ~ ~ ~

When the PE teacher is in class ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
