Mom: You're 28 now. Find someone and get married, or else you'll be leftover. 你已经28了。 找了人嫁吧， 否则你就成残根冷炙了。

Daughter: Mom...I hear you. 妈... 我知道了。

A:  Jeniffer has promised to go out with me! Jeniffer has promised to go...  詹妮弗答应出来跟我约会咯！詹妮弗答应出...

B: Man... I hear you.  天哪，我听见你说的了。

Can you just hear me out? 能让我把话说完吗？

A gentleman will hear others out first and then  deliver his own opinion.
