You would think it's scary that you can just not know a person. It's possible that you have spent years with them, figuring them out, putting up the puzzle pieces of their past together to have a clearer image of what brought them in the current, until you just don't know them anymore. You don't know what they're like anymore, what they've been up to, what their mindset is like. All the things you used to keep each other posted about is just no longer there, nonexistent, barely a probability now.
You would think it's scary that someone can just leave the whole picture, but I think this is supposed to teach us to accept that everything is always changing and they're just no longer who you've known them for. You can always keep the old things you knew about them, the ones that made you admire their humanity, the ones that made you stay. You can choose to see them as strangers or to see them as how you used to look at them. Only this time, the sight isn't going any further. You can only hold on to what you have left of them, and resign to the fact that there's just nothing more. And it's really not a sad thing. I think there's both nostalgia and peace in learning how to pick a certain version of someone, and remember them for it even after they have left. It's something that you still have a hold to, something you can still embrace with what's left of you that they have not taken.
