I've recently started at a new workplace as a System developer. We sit in an "open area" with assigned workplaces where there are walls/ cabinets seperating us.
The coworker behind me was very polite at first meet and shook hands and introduced themselves. Although as my time here elapsed I noticed there seems to be something odd. The person talks to themselves about their code, and sometimes laughs. It's a bit disturbing, as i've noticed by my other coworkers reactions. When this talking begins they will put on their headphones to not get disturbed by the sounds.
No one (except the boss) really knows what they are working with either, as we have 2 breaks a day at 09.00 & 14.00 and usually eat lunch together, we also have afterwork activities sometimes. this person has never attented any of these events during my 9 months here.
I also think there is some phobia included, at one period I had the workplace next to the person, and everytime I would pass to go to on a break/ etc, they would lean forward as to try and avoid any contact. Once I passed the person in a hallway and the person even started draging themselves against the wall just to get as far as possible from me while passing.
I concider this quite disturbing, but also degrading (not sure if right word) in some way, it feels as if I've done something wrong at some point. Although I've tried to be extremely proffesional to make a good first impression on my first real job.
At one time another coworker walked up to this person, without their knowledge and the person got really offended telling them "never to walk up to them that fast and close again". My guess is there is some sort of phobia or maybe even a trauma that has led to this, but I am not sure.
Why is this person acting this way?
Edit As noted above my question was why the person acted that way. I was looking for some kind of information so that I would know how to approach the person if I needed to make contact. To not get yelled at as other coworkers have gotten. If this is not an appropiate question then I can close/ delete it. I was just looking for information.
