It is raining really hard
It is raining cats and dogs
go to sleep
hit the sack or crash!
Super easy
It is a piece of cake
To tease or joke with someone
Pull someone's leg
Get something over with
Bite the bullet
To tell a secret
Let the cat out of the bag
undecisive person
wishy-washy
to be calm or settle down
to be cool as a cucumber
Wishing success
Break a leg
to be ill or sick
to be under the weather
Get 2 things done at the same time
Kill 2 birds with one stone
say something as exactly as someone thought.
To hit the sack/ To hit the hay/
something that you like or are keen on
It's my cup of tea
Very expensive
It cost and arm and a leg
to say a secret or gossip
spill the beans
Looking in the wrong places
Barking up the wrong tree
Something bad turns out in something nice.
A blessing in disguise
someone lazy
a couch potato
To pressure or force one into doing something
Twist someone's arm
to be afraid or disgusted
it gives me the heebie-jeebies
Don't bother the situation or it will make it worse
Let sleeping dogs lie
Starting the day off grumpy
To get out of the wrong side of the bed
To complain about something that happened before
Cry over spilt milk
To ignore someone
to give someone the cold shoulder
To ask what someone is thinking
A penny for your thoughts
