Break the ice
Start conversation
Hit the book
Study hard
Piece of cake
easy
Under the weather
feel sick
spill the beans
reveal a secret
keep in the dark
keep a secret
once in a blue moon
very rarely
Cost an arm and leg
very expensive
Bite your tongue
stop speaking
Beat around the bush
avoid topic
Call it a day
stop working
Hit the sack
go sleep
On cloud nine
very happy
Hit the nail on the hand
exactly right
Actions speak loudaer than words
Actions matter
In the blink of an eye
very quickly
A fish out of water
feel uncomfortable
Break the bank
cost too much
Pull someone's leg
joke around
Go the extra mile
do more
A blessing in disguise
hidden benefit
On the same page
agree fully
Burn the midnight oil
work late
Sit on the fence
not deciding
Bite the bullet
face difficulty
