Hit the hay
Go to bed/fall asleep
The person you are talking about shows up
Let the cat out of the bag
Once in a blue moon
Rarely
Give someone the cold shoulder
Ignore someone
Under the weather
Sick
Barking up the wrong tree
Looking in the wrong place
Sit on the fence
Can't decide
Hang in there
Don't give up/Keep trying
Hit the nail on the head
You got it exactly right!
Break a leg
Good luck!
Go on a wild goose chase
It's impossible/Can't be found
Get out of hand
Cost and arm and a leg
Very expensive
Let someone off the hook
Let someone out of getting in trouble
Pull yourself together
Calm down
Piece of cake
Easy
Fit as a fiddle
Healthy
Don't count your chickens before they have hatched
Don't count on something until you are certain
Miss the boat
Miss an opportunity
Rain on someone's parade
Ruin's someone idea or plans
See eye to eye
Agree
Wrap your head around something
To understand something difficult
Every cloud has a silver lining
To try to find the good in a bad situation
To stay positive during hard times
In the heat of the moment
When someone is feeling overwhelmed or upset and does something without thinking
