Under the weather
Feel sick
A dime a dozen
Something Common
You can say that again
its true
Dont cry over spilt milk
Dont be upset about something you cant change
An apple a day keeps the doctor away
Fruit keeps you healthy
Wrap your head around something
To Understand
Twist me arm
Talk me into something (Convince me)
On it like white on rice
Will do something straight away (Now)
Use your noodle
use your brain
Up in the air
Not decided
Break a Leg
Good luck
Add insult to injury
Make a bad situation worse
Hit the roof
Get Angry
Dont give up your day job
You are not very good
In a pickle
In trouble
Took the words out my mouth
Say something people are thinking
I smell a rat
Something/Someone is untrustworthy
Brush under the carpet
To forget or hide something
As right as rain
Very good
