raining very hard; storm
raining cats and dogs
to wait before you act
hold your horses
not frequently, rarely
once in a blue moon
not backing up words with actions
all bark and no bite
someone imitates (do the same) what you do
copycat
to tell a secret
let the cat out of the bag
to play roughly
horse around
to ask for help where there is no problem
cry wolf
to start over with your plans
go back to the drawing board
being very active
alive and kicking
join in, help
pitch in
something easy to do or complete
a piece of cake
do things the wrong order
put the cart before the horse
not feeling very well; being sick
feeling a bit under the weather
to behave
get your act together
to eat something very fast
wolf it down
speechless
cat ate your tongue
hoping for good luck
cross your fingers
looking nice and fresh
as fresh as a daisy
have doubts
have second thoughts
avoiding the main topic
beat around the bush
all advantages
cut corners
to be in a bad or unlucky situation
up the creek without a paddle
when you feel nervous or too excited
butterflies in my stomach
being very lound
from the top of his/her lungs
