When I’m taking group pictures I like to look at something off camera and make a terrified face.
I never rate any of my apps.
At my last place of work we had one of those mechanical lock things with a number pad. I’d always press a random number after going through it so the next person would get the code wrong the next time and they’d need to try it again.
Sometimes I’d hang around to watch it happen, it always cheered me up.
