Yeah it can be hard to accept. I used to really have trouble accepting it and was always longing to have a group of close friends like so many other people seem to have. But now I've come to terms with it and it is common among all friend groups. I actually read a few times that in all friend groups, there are at least a couple friends that don't feel the same way about each other. One may feel closer to the other and in some cases, there may even be a toxic person. And in a lot of cases, those friend groups that appear to be super close usually never last. They all come apart no matter how strong they think their group is. And I agree that their perspective usually never concurs with ours.
