hold your horses
wait a moment
cost an arm and a leg
very expensive
call it a day
stop working on something
A dime a dozen
Something very common
A blessing in disguise
a good thing that seemed bad at first
Cut somebody some slack
Don't be so critical
Hang in there
Don't give up
Hit the sack
Go to sleep
On the ball
Doing a good job
Miss the boat
It's too late
It's not rocket science
It's not complicated
Pull someone's leg
tricking someone for fun
Pull yourself together
Calm down
Under the weather
feeling sick
Wrap your head around something
To understand something
A penny for your thoughts
Tell me what you're thinking
