you have an exam tomorrow break a leg
the show is excellent, but the tickets cost an arm and a leg
I'm tired,I'm going to hit the sack
I will go on a date with you when pigs fly
don't spill the beans. It's supposed to be a secret
we're all tired,let's call it a day
I've been feeling under the weather this week
I don't see eye to eye with my mother on many things
my last exam was a piece of cake
making me work late on friday was the last straw
