Born with a silver spoon in your mouth
Born to wealth
Eat your words
To have to take back what you said; to admit humbly that you were wrong
Hit the books
Study assignments carefully
Cost an Arm and a leg
Very expensive
Break a leg
Good luck
On the fence
Neutral; Undecided
Once in a blue moon
Almost never
Call the shots
To make the decisions
Call it a day
To stop work for a day
Chill out
Relax. calm down
Keep your shirt on
To remain cool; be patient
No dice
Refused; no
Make your mouth water
To look so attractive and desirable that it makes you want to have it very much
Have your heart in your mouth
To be extremely frightened about something
Ring a bell
To sound familiar
