I'm sorry if this makes me sound like an author who can't take constructive criticism, but there is a difference between CONSTRUCTIVE criticism and saying something rude. If you don't want to vote, that's fine, but don't respond to an A/N that's meant to be casual and lighthearted with a blatant "no" that kills the vibe and then later say you'll be "surprised if you finish this book." That's unnecessary. And don't say something like YOUR English sucks then try to tell ME how to write. That makes no sense. I'm trying to be respectful, and I don't like arguing with people online because that's dumb and immature, but regardless of what you're going through, there are some things you don't have to say. It can make it awkward for other readers as well who just came for fun. Why are you reading a fanfiction like it's an official business document?
Sorry for my rant, but I had to get that out because there is no reason to be rude if you dislike something. There are better ways to phrase things. And if you say certain things just to say them, that's a CHOICE. Someone can read one of my stories completely and say they didn't enjoy it, and that's fine, but say it respectfully. I don't care about a person's opinion, I care about how they say it.
