Aaa, yes. I've been trying to think since this topic popped up which comments bug me the most (short of flat out purposefully rude ones, which are rare), and now that you've mentioned it, this. This is it.
I have a few readers who I think started following me when I got a daily snack and just still haven't read any of the earlier chapters, so they ask a lot of really obvious questions that were very blatantly explained and that anyone who reads my comic would know.
There's two people in particular who do this, but one is at least nice about it... If he asks an obvious question, he at least gives me a "Sorry, I just haven't gotten around to reading the rest yet! Can you explain why ___." And that's fine. I don't mind that.
What DOES bug me is I have this one girl who just seems to like...imply I'm doing a bad job when she doesn't understand. Even though she has told me she hasn't read the first few chapters. So the interactions sort of go along the lines of...
"Why is his shirt purple?"
"Because he's a blank."
"Idfk what a blank is???"
Well...maybe if you just read...literally the first 10 pages of this comic...you'd know.
Another example of this is, I always have a 2 week break between chapters, during which I usually have 3 guest comics, not drawn by me. A few days before my last chapter was released, I made a wall post announcement that, "Hey guys! CoB will be back tomorrow!"
And was literally told "It's not a big deal, you updated just 3 days ago."
....Okay, if you'd actually take a LOOK at the comic, you'd see that update 3 days ago wasn't an actual page of my comic, nor were the past THREE updates because it's been on a break for TWO WEEKS. But she doesn't actually read my comic, so I guess she wouldn't know that, despite the fact that she for some reason expects to know everything without looking at more than a few random pages.
