A: 你最近怎么又请假了？身体不舒服吗？Nǐ zuìjìn zěnme yòu qǐngjià le? Shēntǐ bù shūfu ma?
Why did you take leave again recently? Are you feeling unwell?
B: 不是我自己，是我妈。她腰疼了好几个月，我带她去医院检查了一下。Bú shì wǒ zìjǐ, shì wǒ mā. Tā yāo téng le hǎo jǐ ge yuè, wǒ dài tā qù yīyuàn jiǎnchá le yí xià.
Not me — my mom. She's had back pain for several months, so I took her to the hospital for a check-up.
