What is the silliest thing you did when you think no one was watching?
Sometimes when I'm alone in the washroom, and I'm using the hand-dryer, I would direct the gush of air towards my hair, such that my hair flies up. Kind of like a model photo shot . And I'll smile alluringly (I hope) and look in the mirror, imagining I'm a model or such.
