Agree completely
to see eye to eye
something extremely rare in occurrence
once in a blue moon
something easily done
to be a piece of cake
all the advantages of two different situations and none of the disadvantages
the best of both worlds
To disclose a secret
let the cat out of the bag
used for wishing someone good luck, especially before a performance
Break a leg!
something you say when the person you were talking about appears unexpectedly
speak of the devil
something will never happen
When pigs fly
something is very expensive.
to cost an arm and a leg
To feel under the weather
to not feel well.
to solve two problems at once.
To kill two birds with one stone
To do something badly or cheaply.
To cut cornerst
to make a situation worse.
To add insult to injury
