Many years ago, I gleefully bought a sweatshirt that says “done”. I keep it around with me so that I put it on at any given moment. “Done” can be that I’m celebrating finishing a project. “Done” can be that I’m fed up and not tolerating it anymore. I like to let people guess and think through it, if they even care.
Now, I want a shirt that says “Just go away”. Pretty straightforward message. The question would be whether people would follow that directive. Would people look at my shirt and still stick around? Would people be sheepish? Ah, I love real-world experiments.
