Curtain Camouflage

Polonius: I hide behind curtains 'cause I have a fear of getting stabbed.

—The Simpsons on Hamlet

"That's what tapestries are for."

—The Lion in Winter

There are only so many places a person can hide, but one that's available in most indoor locations is the common curtain. When someone's coming and you've got to get out of sight quick, just duck behind ones of these and you're golden. Oh, drapery—where would Exact Eavesdropping and Wacky Hijinx be without you?

Bonus points if you see the shoes peeking out under the bottom. Triple bonus if the shoes were specifically put there to throw the searcher off the scent.
