Even without the help of next season's poufs, peplums, and koolats, you can still practice looking vacant and unavailable by doing your best model dead-eye. Works at: the post office, parties where you don't know anyone, and weddings where they don't serve cake. Also good for faking a bad Skype connection (as long as you're not a blinker). Just stand in the light and think plastic. Not like Mean Girls Plastics plastic, that's too lively! More like salad-bowl plastic.
