伪装的笑并不虚伪
[wĕi zhuāng de xiào bìng bù xū wĕi]
'Feigned Laughter Is Not Insincere' suggests that even when a person laughs while hiding their true feelings, it isn't necessarily insincere. It implies the complexity of human emotions, where pretending can sometimes be a coping mechanism or a way to protect others from your worries.
