Is it normal that its hard for me to be friends with co-workers

I like farting in groups and seeing everyone scatter

I have had many jobs too, And sometimes the other employees, wanna make it hard for you so you'll quit. Because they feel like your a threat to their job, or their jealous or some bullshit. But just try talking to a few of the nicer ones. And forget the rest.

I suppose it depends on what kinda job you're working. I've had certain jobs where little to no skill was required and I didn't make a lot of friends at those jobs because it was hard to find people with whom I shared common interests.

Your co-workers make you hatd bcuz ur a nasty pervert

I think so. I've always found that when I'm in "work mode" I'm kind of playing a role and acting a certain way so I might be a little more guarded and less casual, which just makes it different relating to people at work vs real life. You might find this too.

Also, I've worked with quite a few people who make no effort being friendly because they just don't want to be at work.
