随便他们怎么说，反正我不在意别人的想法。

Suíbiàn tāmen zěnme shuō, fǎnzhèng wǒ bù zàiyì biérén de xiǎngfǎ.

Let them say whatever they want—anyway, I don’t care what other people think.

没事，你慢慢吧，反正我有空。

Méi shì, nǐ mànman ba, fǎnzhèng wǒ yǒu kòng.

It’s fine—take your time; I’m free anyway.

你可以试试这种方法，反正也没什么损失。

Nǐ kěyǐ shì shì zhè zhǒng fāngfǎ, fǎnzhèng yě méi shénme sǔnshī.

You can try this method anyway, there's no harm in it.
