My friend Ted and I have been super close since we were six years old. He was in town last night, so we got together for dinner. Our lives took much different trajectories – Ted is married with four kids – but it doesn’t matter when you have chemistry. There was never a lull in the conversation, and I was sad to drop him off at the airport.
You don't have to have anything in common with people you've known your whole life, because you've got your whole life in common.
