I don't know if something is missing from this article or if I have a very restrictive view of friendship. For example, when I was in college, there were a few people with which I talked pretty much everyday, had lunch with them, went to class with them. However, I don't really consider them my friends. They were a bit more like "colleagues". We never saw each others outside of college, and spending time with them doesn't fill me with energy like when I spend time with my friends. There are lots of things that they don't "get" if I talk about them, not as in "understand" but as in "get" on a fundamental level. Following the framework of the article, either "attention" was missing, or something is missing from the article. In French we have an expression, "atomes crochus", which would be equivalent to "chemistry" in English. Without that, friendship isn't really possible for me, I'll always get "stuck" only at a certain level with those people. There's no mention of chemistry at all in this article. I get that it's a bit unfair, you can't decide to have good chemistry with someone, but at least for me that's how things are.
