On thin ice
If you make another mistake you'll be in trouble
Easy does it
Slow down
Jump on the bandwagon
Follow a trend or do what everyone else is doing
Cutting corners
Doing something poorly in order to save time and money
Like two peas in a pod
Always together
It takes two to tango
One person isn't responsible- both people are
That costs an arm and a leg
Expensive
Let the cat out of the bag
Tell a secret
It's raining cats and dogs!
Heavy rain
Break a leg!
Good luck
That ship has sailed
It's too late
Calm before the storm
Something bad will happen but right now it is calm
You can't have your cake and eat it too!
You can't have everything
Hang in there
Don't give up!
