句中使用了比较级结构better at doing sth. than，强调在隐藏情绪方面他人与“你”之间的能力差异，表达含蓄且富有洞察力。
When you see others laughing, do not assume that you are the only one suffering in the world. Often, others are simply better at concealing their emotions than you are. If you feel inferior in every aspect, remember that we are ultimately ordinary people. We spend our lives pursuing happiness, and no one refuses it. It is as natural as not refusing a warm coat when cold or bread when hungry.
当你看到别人欢笑时，请不要误以为世界上只有你一个人在承受悲伤。很多时候，旁人只是比你更擅长掩饰内心的情绪。如果感到自己处处不如他人，请时刻铭记，我们终究只是平凡的普通人。我们的一生都在追寻幸福，没有人会拒绝幸福，这就像寒冷时不会拒绝温暖的棉衣，饥饿时不会拒绝充饥的面包一样自然。
