to go to bed
hit the sack
it's used to wish someone luck
break a leg
to decide that you have finished doing something
call it a day
to feel ill
to be under the weather
tell people secret information
spill the beans
agree with each other
see eye to eye
something that is very easy
a piece of cake
the latest problem in a series of problem, that makes a situation impossible to accept
the last straw
to be very expensive
cost an arm and a leg
something that will never happen
when pigs fly
