Body parts
To have your head in the clouds
Lost in thought. Daydreaming. Not in reality.
Feeling blue
Feeling sad
Let the cat out of the bag
Tell a secret
To feel sick
Piece of cake
Really easy
Put your foot in it.
Make a mistake. Say or do something embarrassing
See red
To be angry
Hold your horses
It's a breeze!
It's easy!
Walk on eggshells
Be careful with your actions and words
Cost an arm and a leg
Really expensive
Have a green thumb
Be good at gardening
You feel nervous
As right as rain
To be healthy
Spill the beans
Tell a secret
I'm pulling your leg
I'm joking
In the red
You owe money. To have debts
In the dog house
In trouble
To do something without worrying about it
Big cheese
Very important person
