I just doorslammed my father two months ago. Even though I eventually want to see him again, I think there's a high chance I'll never open that door again. There's a friend I've doorslammed after high school, for the reason that he forgot all about our group when he joined a fraternity. But in this case, doorslamming means that I can still see him, but I won't allow us to be friends again. I see it as a pragmatic door slam.
