to feel blue
to feel sad
to drop the ball
to make a mistake or miss and opportunity
the best of the best
Bend over backwards
to do anything it takes to help someone
When pigs fly
something will never happen
to be all smiles
to be outwardly happy
out of left field
completely random
to have sticky fingers
to be a theif
Beat around the bush
to not get straight to the point
It takes two to tango
Something requires two people to do
over the moon
to be extremely happy or excited
a hail mary
to be a last ditch effort to do something, not expected to work
to go back to the drawing board
to start over
Barking up the wrong tree
looking in the wrong place, asking the wrong questions
By the skin of your teeth
to succeed in something but only barely
chip on your shoulder
to have confidence
jump the gun
to do something too soon
to bite the bullet
to endure or face a tough situation
Once in a blue moon
something happens very rarely
Put a sock in it
to be besides oneself
to be shocked or flabbergasted
par for the course
when something is expected within a situation
to butter someone up
to flatter them in order to get something you want
Run on fumes
to continue to do something while being exhausted
The lights are on, but nobody's home
When someone is blanking, or not behaving intelligently
