Over the years though, it felt more and more hollow. We've had time to step back and think lately. I realized what was missing was emotional openness and that comes with a little vulnerability. While being friendly with workmates is nice, it isn't the place to show emotional vulnerability. I had set myself up to never be able to turn associates into friends.
It finally clicked as to why people keep their work and friends separate. I'm glad you found your groove. The quality of life that comes with having deep friendships is incredible. I hope stories like these inspire others to take a step toward realizing deep friendship.
