That’s a piece of cake
That’s as easy as pie!
I can do it with my eyes closed
請你客氣點
Who do you think you’re talking to?
Don’t get fresh with me (get fresh with 大多用于母親對孩子的斥責之時)
等著瞧
you’ll see. / Time will tell。
多管閑事
(It is) None of your business.
Mind your won business.
Who asked you?
This has nothing to do with you.
別狗眼看人低
Do I look like a fool?
Who do you think I am?
What kind of a fool do you take me for?
不要告訴別人
Don’t tell anybody (about it).
This is just between you and me.
This doesn’t leave this room.
This is for your ears only.
