毕竟你我不同心事肿么会懂
[bì jìng nĭ wŏ bù tóng xīn shì zhŏng me huì dŏng]
Translating roughly into 'since we have different heart concerns, how can I understand?' This highlights differences between two people's feelings or viewpoints, emphasizing challenges of mutual empathy when personal contexts do not align well.
