Cross your fingers
Hope for something
Pig out
Eat a lot
Time flies
Time passes very quickly
Night Owl
Someone who likes to stay up late
Easy as ABC
Very Easy
Get cold feet
Be nervous
Cat got your tongue?
Why aren't you talking?
Call it a day
To be finished with something
Kill two birds with one stone
Solve two problems with one action
It's in the bag
When something is certain
Fell on deaf ears
People wouldn't listen to something
Busy as a bee
To be very busy
Down to the wire
Wait until the last minute to do something
Early bird gets the worm
It's important to start early
Pass with flying colors
Pass with a high score
I'm all ears
I'm paying attention
Get off your high horse
Stop thinking you're better than other people
Beat the clock
Finish something just in time
A little birdie told me
I heard a secret
Draw a blank
Can't remember
Have a heart to heart
Have an honest conversation with someone
Cry crocodile tears
To pretend to be upset
Wasn't born yesterday
Not easily tricked
Birds of a feather flock together
When a group of people have similar interests
Cool as a cucumber
