Please stop touching my laptop screen. Just don't. Every time you do it, it leaves a big greasy iridescent blot that I have to wipe off later with alcohol wipes and lint-free cloths, which is a pain in the ass. My screen picks up enough dust and dirt as it is. Just point and describe. I understand what you want me to see without your insistently poking it. No touchy. No touchy! Stop doing this, and I will stop sneezing on your eyeglasses or removing the bricks from your house one by one.
