hold your horses
wait a moment
Hit the sack
Go to sleep
Hang in there
Don't give up
By the skin of your teeth
Just barely
Pull someone's leg
To joke with someone
There are other fish in the sea
It's OK to miss this opportunity. Others will arise.
Saving for a rainy day
Saving money for later
Let the cat out of the bag
Give away a secret
Go back to the drawing board
Start over
cost an arm and a leg
very expensive
Take a rain check
Postpone a plan
Actions speak louder than words
Believe what people do and not what they say
Pull yourself together
Calm down
The ball is in your court
It's your decision
On thin ice
On probation. If you make another mistake, there will be trouble.
Wrap your head around something
Understand something complicated
Spill the beans
Give away a secret
We'll cross that bridge when we come to it
Let's not talk about that problem right now
You can't judge a book by its cover
This person or thing may look bad, but it's good inside
It's raining cats and dogs
It's raining hard
break a leg
good luck
The best thing since sliced bread
A really good invention
Give someone the cold shoulder
Ignore someone
It's a piece of cake
It's easy
Under the weather
Sick
