I'm actually not diagnosed or anything, but I do identify with this. I'm always startled when someone else refers to me as a friend when I would not have ranked them higher than a co-worker or acquaintance. How do you become someone's friend without even noticing it, and how can we be friends if I haven't accepted this label. How can people who have only been on a few dates or hung out a couple of times be 'in a relationship'? I've fallen into relationships completely by accident before because I never realized that was the dynamic the other person had attributed to our time spent together. Likewise, at what point am I allowed to label someone else as a friend or significant other? Where is that line? I have had friends that I have known for years, and I am confident in calling them best and dearest friends, but new people? At what point do they stop being just people that you know and earn the title of friend? Likewise, at what point are you considered a friend? And how can you know when it seems to be a shifting line that is different for everyone? If you ask them directly if you are friends then they look at you like you are an alien, and then you have to wonder if they only agreed because they considered it a socially polite thing to do, or they get insulted because how can you not know that you've been friends for ages?
People are hard.
