I had two of my colleagues visiting me yesterday just to hang out for the evening. It's nice being able to invite people over whenever I want. When we were still living together with my wife it wasn't really possible as she didn't feel comfortable having people she didn't know visiting. It was a mutual feeling as I felt awkward as well when her friends or colleagues visited.
Another thing that was preventing me from inviting these people was the fact that I was their direct supervisor. It just felt a bit awkward having that kind of relationship burdening the camaraderie. Now that I don't have such responsibilities anymore in my new role I can feel more relaxed spending time outside of work with them.
It was a great evening overall and we even managed not to speak too much about work during the night.
