I apologized for blocking you months ago on your Twitter, I'm sorry for doing that.
You're free to block whoever you want to, especially since blocking is more than just a tool of anger unlike most of the internet seems to think it is
I really don't know you very well, but if you need to block me for whatever reason to help your mental health or just don't agree with me for whatever reason that's completely valid and ok
I'll be honest, I really don't really know you... I don't recall having very many personal conversations with you. It takes a lot for me to consider others friends.
I'm sorry you felt ignored, I have severe social anxiety and it can lead to not replying to things. It's never personal to anyone when I don't reply.
