wear one's heart on one's sleeve（把情感表露出来）
   
    意思是"to make one's intimate feelings or personal affairs known to all（张扬，外露，坦率）"，尤指感情上的外露；其实也就是"expressing your emotions freely and openly ...（大胆的说出你的真实感受）"。
   
    请看例句：
   
    She's a shy person. She's never been one to wear her heart on her sleeve.
   
    她是个害羞的人，从来不敢把心里的真实想法表达出来。
   
    Alan: This is life and death. Your wife is lying in a coma. You, you don't even make a pretense of caring, do you?
   
    Alan：这是生死大事，你的妻子正处于生死状态，你连假装关心下都不行吗？
   
    Claus: Of course I care, Alan. It's just, I don't wear my heart on my sleeve.
   
    Claus：当然，我当然关心啦，只是我不擅于言表而已！
   
    BTW: 这段对话是出自《Reversal of Fortune（命运的逆转）》
