I am not a shy person, but I still like to keep to myself, I am just not that into socialization.

Everywhere I've worked I've only made friends with those that sat very close to me, like in the neighboring cubicles or whatever, even if I didn't have any project in common with them, but my relationship with those that were working on the same project as me was strictly professional.

Recently, my employer installed a rec-room with table tennis, foosball and pool table etc. And ever since then the whole office's morale has sky rocketed, especially mine. Now, I almost always spend at least 2-3 hours down there daily playing those games and I have gotten to know and have made friends with a lot of my co-workers, something that I wouldn't have done ordinarily ever.

Now my point here is that, I've always found socialization to be a bit out of my comfort zone, I always thought it to be a bit bothersome, but it would seem that all I really needed was the right environment, it is very hard to get to know others around you in a strictly professional environment, so having dedicated places in your office for things like group activities that can help relieve stress and allow people to get to know each other better outside the work environment can be extremely helpful.
