the last straw 忍无可忍
A:That was the last straw!
B:Why did you say that? Did your girlfriend do anything wrong?
A:She refused to see me. She must have fallen in love with another guy.
B:I don’t believe it. Talk with her, will you? There must be some misunderstanding between you.
甲:真是让人忍无可忍!
乙:你为什么这么说?你女朋友做什么错事了吗?
甲:她拒绝见我,她一定是爱上别人了。
