being completely in love
what is head over heels
unexpectedly
what is out of the blue
raining heavily
what is raining cats and dogs
being sick
what is under the weather
following a rule
what is by the book
Get to the point
what is cut to the chase
eager to listen
what is all ears
in trouble
what is in hot water
to give up
what is throw in the towel
difficult situation
what is bite the bullet
too late
what is miss the boat
aim high
what is shoot for the moon
calm down
what is out yourself together
