Are you ever in the office, working ever so diligently, only to be interrupted by a stray coworker? SOMETIMES, that stray coworker doesn't even notice the over-the-ear headphones you wear specifically to thwart off unwanted chatter? Don't worry, THIS is your solution. Simply point to your brand new foiled print and send those strays away! (Unless they are stray dogs or cats, take those home!)
Disclaimer: Probably ineffective towards children and spouses, but maybe worth a shot!
