Many of my most treasured friendships started in the workplace. Fourteen years into my career as a journalist, I’ve found there’s something magic about the closeness that can be found in work friends.

For people who work closely alongside their colleagues, these adult friendships can feel akin to those made in school, university dorm rooms or sharehouses. Once most of us graduate and begin living alone, or with a partner, there are few places beyond the workplace where you can spend near-constant time with a friend.
