That makes sense. And I agree that they weren't super close. I guess I just don't need to me. The Avengers, for the most part, to me are "work friends." Acquaintances who work together and therefore know each other pretty well, but their friendship is based on work and they aren't so likely to meet up outside of work things (apart from the occasional shawarma meal). Their is still a relationship there that gets torn in Civil War and needs repairing so they can work together again. But I don't think they are best friends in the movies, and I'm not sure the creators intended them to be.
