Some colleagues you spend a lot of time with and and there is still a bond even if you are not real friends that would spend time together outside of work.

Sometimes my colleague needs to went about a project that is going bad or a person that is making their life difficult and sometimes I might do that as well. You listen and sometimes you discuss solutions but sometimes it just venting about a situation you both know is shitty.

Just don't become they guy/girl who is always negative or talking shit about people though.
