You grip the jar like you're performing surgery. You twist until your hand goes numb. You switch hands, convince yourself the lid is definitely loosening now—it isn't. Then your partner walks in, takes it, opens it one-handed while asking if you want tea. The jar wasn't sealed. You were just weak.

I hand the jar to my roommate with the confidence of someone who's already given it everything. He twists it counterclockwise—the direction I'd been twisting it—and it opens instantly. I watch my entire upper body strength get invalidated in 0.3 seconds. He hands it back like he just returned a pen, and I'm standing there realizing the jar wasn't sealed; I was just built wrong.
