没有勇气 have no courage
have one's heart in one's boots
pluckless
- 你们谁也没有勇气正视这一点。
None of you had the guts to face that. - 是的,我没有勇气再去拔另一个了,即使牙医建议我必须拔。
Yes. I don't have any courage to pull another one even though the dentist has told me that I should do it. - 但是更痛苦的是你爱着一个人但却没有勇气让他知道你的感觉。
But what is more painful is to love someone and never find the courage to let that person know how you feel.
