Friends and aquaintances

Long time since I've written in here. So today I saw a group of friends and people I haven't seen in long while. While it was nice to see some faces again, I sometimes wonder who I am really close with and who are my true friends. Sometimes I wish I had that ability to be able to connect with other people more. Aside from that, sometimes there's nuances I feel as someone on the outside looking in. I have this one friend who's personality and character comes across as someone who's antisocial and hates everyone. He doesn't really hate everyone, he just doesn't care. It seemed though as someone that most people remember and gave hugs to. It just made me feel how at the end of one school year people were talking about the people who they remembered and was close to and I wasn't really mentioned and was under the impression that I was closer to these people than maybe I really was.
