Break a leg
Good luck
You will have bad luck
Go break your leg
Cut somebody some slack
Don't be so critical
No one cares
Cut them with a slack
Ok
A Blessing in Disguise
A bad thing
A blessing that is hard to find.
A good thing that seemed bad at first
A good thing
Cutting corners
Doing something poorly in order to save time or money
Means you took a short cut
Beat around the bush
Say what you mean
Mean what you say
Avoid saying what you mean
Bite the bullet
To get something over with sooner rather than later
Doing something hard is rewarding
Biting bullets of bad for your teeth
A dime a dozen
Something uncommon
Something common
Better late than never
You never came
Better to arrive late than not to come at all
