妈妈:
Son, the garbage needs to be taken out. Don’t just sit there, go do something about it! 

儿子,垃圾该拿出去了。你就别光坐在那儿了,去做点事吧!
儿子:
I am not just sitting here. I am busy thinking whether should I buy my girlfriend a car. 

我没有光坐在这儿,我在想我是不是该给我女朋友买部车。
妈妈:
That's going too far. You only earn RMB 1800 per month. 

那太过分了!你每个月才挣1800元。
儿子:
Who do you think you are? Mind your own business. 

你以为你是谁啊?管好自己的事吧。
爸爸:
Don't talk to your mother that way! 

别跟你妈那么说话!
儿子:
I'm sorry,mum. 

对不起,妈妈。
爸爸:
That's more like it. 

这才像话。
