The great clarinet crisis or I am responsible-I just can't remember that I am

After finishing her homework, Kris went to practice her clarinet. It was not here, oh no! She left it in the bathroom after b-ball practice. Tears and worry. Try to figure out who to call. There is no one. We drive over to the school, finally find an unlocked door. It is not in the bathroom or the gym. Where is it? She checked her locker and there it was waiting for her. GRRRRRR.
