何必 and 何苦: why bother
何必 + verb · 何苦 + verb
何必 is the rhetorical 'why' for a needless action: 离这里很近，何必打车. 何苦 is 'why put yourself through it', for wasted effort: 身体不舒服就请假吧，何苦硬撑着上班？ A verb comes right after each of them.
Examples
- 你自己做得很好，何必在意别人怎么说？ Nǐ zìjǐ zuò de hěn hǎo, hébì zàiyì biérén zěnme shuō? You did well yourself, so why care what others say?
- 身体不舒服就请假吧，何苦硬撑着上班？ Shēntǐ bù shūfu jiù qǐngjià ba, hékǔ yìng chēng zhe shàngbān? If you feel unwell, just ask for a day off — why wear yourself out?
- 离这里很近，何必打车？ Lí zhèlǐ hěn jìn, hébì dǎchē? It's a short walk from here, so no need to take a taxi.
