Seriously, just say this OP. You being an introvert has nothing to do with saying the bare minimum. It’s honestly insulting using that as a crutch, introverts just don’t like extended social interaction and need time to recharge. We aren’t timid or frozen.
You do realize that the vast majority of “actually normal people” from your comment are or have been in relationships? Like what is your definition of that, I don’t think it’s what most would think.
