Have cold feet
To feel scared
Hold your horses
Be patient, wait
Crying crocodile tears
Fake crying
Heart of gold
kind, caring, generous
Raining cats and dogs
Raining hard
On top of the world
Very happy
Going bananas
acting crazy
In a pickle
To be in trouble
Butterflies in my stomach
Feeling nervous
I am all ears
To pay attention
It is a piece of cake
It is easy
Down in the dumps
Feeling down
Let the cat out of the bag
Tell a secret
She is a peach
Sweet, nice, helpful
