Learn Hardcore Russian: Неужели тебе тоже надоело читать грубые комментарии под постами? - Did you really get tired of reading rude comments under posts too?

Неужели introduces a question with surprise / disbelief, like “Really? Can it be that…?” It often implies the speaker didn’t expect the answer to be “yes”.

Неужели тебе тоже надоело…? ≈ “Really, you’re tired of … too?” Comparison:
Правда? is more neutral: “Is it true?” / “Really?”
Разве…? also suggests surprise, but often with a shade of “But isn’t it the case that…?” or “I thought the opposite”.

Why is it тебе (dative) instead of ты (nominative) or тебя (accusative)?

With надоесть (“to become annoying / to get tiresome”), Russian commonly uses a structure like:

(кому?) надоело (что делать?) So the person who feels “fed up” is in the dative: мне / тебе / ему / ей / нам / вам / им. Example pattern:
Мне надоело ждать. = “I’m tired of waiting.”

Why is it надоело (past tense) if the meaning is “Are you tired of…?” right now?

Russian often expresses a current state (“I’m sick of it now”) with надоело (past neuter), because the idea is “it has become tiresome (by now)”. So тебе надоело читать… literally is like “it got boring/annoying for you to read… (and it remains so now).”
