Learned response
I was trying to fix my nub. The "clit-mouse" in the middle of my laptop keyboard. My cursor keeps drifting down and right, so I was pulling it up and left. I managed to pull it right off. At the same time, I was listening to some version of the Super Mario Bros theme on YouTube. What would you do? Just stick it back on? Not me. Without thinking about, I blew into the bottom of the nub, blew into the keyboard, and then stuck it back on. I'm well conditioned.
