Naruto isn't even annoying anymore, I've just become numb to him..I have to to get through watching his stupidity sometimes. I mean, I like him, but damn..he can be overbearing at times.
Edit: But this time was different imo. We were approaching an "uncomfortable" moment for Kakashi (just look at his demeanor and Gai's reaction), so I felt Kishi said that was "enough" vulnerability for Kakashi in one chapter. Naruto may or may not have also sensed Kakashi's uneasiness and decided to "get his sensai's back".
