2. If someone asked me this question, I would think it's not up to me to decide such a thing for someone else. I would give the options as I see them, that would be my way of trying to help I guess, by looking at it from different angles. I don't see why that's confusing? I actually find it odd that someone would expect a completely direct, concrete answer to something like that. It's not for someone else to decide, and it doesn't have one answer. Surely it's best to see it from more than one angle?
3. No, I'm not annoyed by other N's (in general) at all.
4. N's make sense to those who understand them.
