My old job I didnt hang out with my coworkers for 2 years. In year 3 I decided to hang out with them.. Had a pretty good time. Now they became good friends and I still hung out with them even though I am at my current job. Afterward, they started acting different towards me so I cut them off.
Now at my current job, I am there for 8 hours and leave, it may be b/c I started back in May. I went out with some back in July, had a great time, took shots, drank and had a fun. I was still aware of my element as I was "the new kid" in the office and didnt want a reputation, or getting back that I cant hang/hold my liquor.
I'm the type of dude, I have to feel you out first. If I think something isnt right with you, I'm not hanging out with you.
