You're getting paid to be friends with your co-workers? Or are you being paid to work, and work, like many other situations where multiple people gather and share experiences and spend time together are also places that people tend to form friendships in. You had friends in school that you stopped maintaining the friendship when you stopped attending school together I'm sure. Were those people not actually your friends? How long does a "social interaction" have to last, and over what distances before it becomes a "friendship" instead of a "transactional relationship"? If it ever ends was it never a real friendship? It's certainly possible to view every relationship you build with people that you share circumstances with as transactional relationships, but that to me seems like a good way to never actually build a friendship with anyone.
