ELI5 Why is a repetitive motion, such as drumming a finger on the table, annoying for others but not for ourselves?

Those type of actions are about soothing or entertaining yourself. You get positive feedback from the noise or motion. Other people just get an annoying click, tap, or track suit rustling as you bounce your leg up and down in 3rd period noise. Great for you as it works out your nerves, not for others because it's just a noise or motion.
