Saving money for later
It's raining cats and dogs.
It's raining hard
We pigged out.
to eat a lot or too much
Take a rain check
Postpone a plan
a fish out of water
in a strange situation
Why do you have such a long face?
Why do you look sad?
You can't judge a book by its cover.
This person or thing may look bad, but it's good inside
Under the weather
Sick
I'll keep in touch.
to communicate or continue to communicate with someone by using a phone or writing to them
It's not my cup of tea.
not the type of thing that you like:
hit the roof
to become extremely angry
I'm in hot water.
To be in or get into a difficult situation.
pull someone's leg
to tell someone something that is not true, as a joke
hold your horses
wait a moment
cost an arm and a leg
very expensive
Once in a blue moon
Rarely
There are other fish in the sea.
It's OK to miss this opportunity. Others will arise.
It's a piece of cake.
It's easy
On the ball
Doing a good job / aware of any changes or developments and quick to react to them
break a leg
good luck
Take it with a grain of salt.
Don’t take it too seriously
break the ice
do something to make people feel more comfortable
We see eye to eye.
to agree with each other
I'll keep my fingers crossed for you.
to hope strongly that something will happen, good luck!
It's on me.
I'll pay for it.
a dime a dozen
Something very common
Let the cat out of the bag
Give away a secret
The ball is in your court.
It's your decision
Miss the boat
It's too late
Give someone the cold shoulder
Ignore someone
Spill the beans
Give away a secret
A perfect storm
the worst possible situation
hit the books
study hard
Hit the sack
Go to sleep
call it a day
stop working on something
