Go to school

You decided to walk to your school. After a while you get there and enter the building.

"I wish I am right in time for gym class to start"

I walk into the locker room and already see some of my class mates. Getting dressed for the gym class.

"I wish I am all alone here and only the girls show up to this gym class. And me of course."

I walk into the gym and see that my wish actually worked and there are only girls there.
