I ran into this phrase in a Think Geek ad, Googled it, and found this:
“One source characterizes the relationships as “platonic, close, opposite-sex couplings, with no romantic strings attached.””
Let me just say, I’m happy that my “work spouse” is my actual spouse. (And, just to be clear, it’s non-platonic and there are romantic strings attached! 🙂 I <3 working from home!
