When an attempt fails and it's time to start again.
Back to the drawing board
Suspect that something is wrong in a particular situation.
Smell a rat
Something small and unimportant, compared with something else.
It's a drop in the bucket.
Stop yourself from saying what you really think
Bite your tongue.
When someone doesn't want to make a decision.
Sit on the fence
Someone who is very annoying.
A pain in the neck
When someone accidentally or unintentionally gives a secret away.
Spill the beans
Tell a secret.
Let the cat out of the bag.
Very similar, especially in appearance.
Like two peas in a pod.
To marry someone
To tie the knot
When someone misses his or her chance
Miss the boat
"Don't make plans for something that might not happen".
Don't count your chickens before the eggs have hatched
To be in love with someone when you see them for the first time.
Love at first sight
Come to the point, leave out details.
Make a long story short.
Deal with a problem if and when it becomes necessary, not before.
Cross that bridge when you come to it
Don't judge something primarily on appearance.
Can't judge a book by its cover
