Is there some kind of graphic already available I can print out and cut out and laminate, about the size of the credit card so it fits well with them in my wallet, that conveys the sentiment I CAN HEAR THE SOUND LEAKING FROM YOUR EARBUDS FROM HERE ? Something I could pull out and hold up in front of someone to communicate something they may be completely unaware of, and might even be mortified to find out if they were good human beings? Something pretty neutral, maybe even friendly, that I could carry around?
There must be. I wonder what the reactions will be.
