I like something
It's my cup of tea
Impossible
When pigs fly
Get luck
Break a leg
talk about someone, and that someone came
speak of the devil
do not see anything
blind as a bat
I am nervous
have ants in your pants
I can not speak properly
I have a frog in my throat
You know something before other people
A little bird told me
I do not understand
It's all greek to me
In a different place act like the people of the country
When in Rome do as romans
I do not feel well
I am feeling under the weather
Be very cool
Cool cucumber
Have a favourite
apple of my eye
When you get red very easy
Beet red
all ears
listen very carefully
do not have money
go broke
when you copy something from someone
be a copycat
when you have second thoughts
cold feet
very expensive
costs an arm and a leg
are you shy?
cat got your tongue
do not see what you have in front of you
be blind as a bat
a problem that everybody knows
the elephant in the room
one time only
once in a blue moon
you want to know something before anyone else
curiosity kill the cat
find the solution to two problems with only one step
kill two birds with one stone
