hold your horses
wait a moment
The ball is in your court
It's your decision
Hit the sack
Go to sleep
Give someone the cold shoulder
Ignore someone
cost an arm and a leg
very expensive
On the ball
Doing a good job
Saving for a rainy day
Saving money for later
Hang in there
Don't give up
Once in a blue moon
Rarely
Under the weather
sick
Better late than never
Better to arrive late than not to come at all
call it a day
stop working on something
break a leg
good luck
