hold your horses
wait a moment
cost an arm and a leg
very expensive
call it a day
stop working on something
A blessing in disguise
a good thing that seemed bad at first
Cut somebody some slack
Don't be so critical
Go back to the drawing board
Start over
Hang in there
Don't give up
Hit the sack
Go to sleep
Give someone the benefit of the doubt
Trust what someone says
Let someone off the hook
To not hold someone responsible for something
On the ball
Doing a good job
Make a long story short
Tell something briefly
It's not rocket science
It's not complicated
Pull someone's leg
To joke with someone
Pull yourself together
Calm down
Under the weather
Sick
