I work in a shared office space. I have two coworkers who frequently (usually multiple times per day) will look at my computer screen either while I'm working or just looking at something on the internet and start commenting on whatever they see, even ads that have nothing to do with anything on the side of the webpage. Sometimes they'll tell me to click on the ad so they can see what it is or ask me to look something up for them on google (even though they all have their own computers). One coworker even parks her chair to point directly at me and stares at me sometimes. Both sometimes stand behind me and look over my shoulder for no reason.
I find this behavior obnoxious and irritating and suggestive of social retarrdation on their part, but maybe I'm overreacting? What do you guys think?
