Barking up the wrong tree
Be glad to see the back of
Cry over spilt milk
A penny for your thoughts
Bite off more than you can chew
Ball is in your court
Back to the drawing board
Actions speak louder than words
Caught between two stools
Don't put all your eggs in one basket
Do not put all your resources in one possibility.
To take on a task that is way to big.
When you complain about a loss from the past.
When someone finds it difficult to choose between two alternatives.
A way of asking what someone is thinking
When an attempt fails and it's time to start all over.
Accusing the wrong person
It is up to you to make the next decision or step
Be happy when a person leaves.
People's intentions can be judged better by what they do than what they say.
