Pulling my leg
Joking
Sleep on it
Think about something
Cost an arm and a leg
Expensive
In hot water
In trouble
A piece of cake
Easy
In the same boat
Same situation
Let he cat out of the bag
Told a secret
Get cold feet
Nervous
Could eat a horse
So hungry
The straw that broke the camel's back
The last bad thing
Over the moon
Two peas in a pod
Best friends. A lot alike.
Bend over backwards
Do a lot for someone
Bite your tongue
To be quiet. To not say something.
Cat got your tongue?
You are being quiet.
Sweet tooth.
Someone who likes sweets
Music to my ears
Something that I am happy to hear
Cry baby
Someone who is complaining a lot
White as a ghost.
Looking really pale
Sick as a dog.
Really sick
Hold your horses
Hold on. Wait.
Woke up on the wrong side of the bed.
Really cranky
I'm all ears
Listening
A dime a dozen
A lot of something. Very common.
Crystal clear
I understand
