"It is important to note that..." doesn't meant that something is important.
"I have fixed every edit you suggested" doesn't mean that no more edits are required (or even that you actually fixed what I suggested).
"I've been ill the last three days before the deadline" isn't an acceptable excuse for not having used the previous thirty days before that, also included in your deadline.
"I don't know how to improve this text" is not a cue for me to jump in with a cure.
*Note: in this case I am myself the wiser. Or the unwiser. Or at least the person in need of taking my own advice. By admitting this I am, of course, in no way suggesting that there might not also be others in need of taking this advice...
