Confucious was a cool cat!

Last night our friend Erin was home from university. She came over with some questions for us on English Idioums. She brought with her a huge stack of papers that she had to memorize. Can you believe they make them memorize this stuff?? She also had a book of confucious since many chinese idioums are based upon his teachings. She told us some of the idioums she had were translations from chinese and she wanted us to guess which ones were english.
Here are a few , see if you can tell! I think its preety easy to find the chinese ones! Tell me what you think.

Down in the mouth, lose one's spirit, with tail between legs.
You can't make a crab walk straight
Care kills a cat
win win co-operation ( we told her it probubly should be situation)
Even a dragon finds it hard to control a snake in its old haunt
Powerful outsiders can hardly afford to neglect local bullies.
talk of the devil and he comes ( maybe speak of the devil?)
speak the truth, call a spade a spade ( this one I had to include for Grandma Charboneau!)
Skin a flea for it's Hide
a slow sparrow should make an early start ( Maybe the early bird gets the worm?)
and my favorite,.
Life begins at forty! ( Erin asked me, do you know who says this? I said , "umm old men" and she said no "Confucious first said this". "Wow Confucious was a cool cat " I said
She then asked me what cool cat means and informed me that in china the saying is cool dog. So if you are ever needing to use 50's slang in china make sure you get it right. Cool Dog!
