Nuts
Crazy
Better late than never
Better to arrive late than not to come at all
Hang in there
Don't give up
Under the weather
Sick
Hit the sack
Go to sleep
Hold your horses
Wait a moment / Calm down
Once in a blue moon
Rarely
Go back to the drawing board
Start over
Give someone the benefit of the doubt
Trust what someone says
Call it a day
Stop work on something
Have your head in the clouds
Be distracted
It takes two to tango
Both are involved in a bad situation
Cut somebody some slack
Don't be so critical
Cost an arm and a leg
Very expensive
The elephant in the room
An issue or problem someone is trying to avoid
Put something on ice
Put a project on hold
Pull yourself together
Calm down
Break a leg
Good luck
