Who's your Избранное character? Were Ты sad when [insert character died]/Did Ты cry when [insert character]died? Who is hot? Do Ты hate [insert character]? Why doesn't anybody like [insert house/character/book/movie]? (Usually this pertains to Ginny.) Why do people like [insert house/character/book/movie]? Which house would Ты want to be in? [insert character/house/book/movie] или [insert character/house/book/movie]? Should [insert character] have married [insert character]?
Mostly because all of those (^) Вопросы have been asked at least twice, for almost every character that has ever been mentioned in the entire series. Not to mention that they're very generic Вопросы to begin with.
"Who's hotter?" "Who would Ты rather date?" "Who's your Избранное character?" "Which house is better?" "Who should have ended up with [insert character here]?
These are the ones that where on the вверх of my head. The "who's hotter" and "who's better with who" Вопросы annoy me the most.
