I don't mind them, unless they ruin the flow if it goes something like
Naruto: Blah blah blah Sakura
----
Sakura ~sneeze~
----
Naruto: Keep going with long scene of blah blah.
Nose bleeds are almost as bad, but thats because authors tend to be all ~nosebleeds~ or "He felt his nose bleeding" rather than describing it loosely and letting us realize it is a nosebleed. Ya dig?
