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