EASY
It’s raining cats and dogs
It’s raining hard
I’m over the moon
I’m so excited/happy
Hit two birds with one stone
To solve two problems with one action
Break a leg
Wishing someone good luck
You hit the nail on the head
You got something correct
We have to break the ice
Do something or say something to make people feel relaxed or comfortable.
That costs an arm and a leg
It’s expensive
That’s a piece of cake
That is so easy
Barking up the wrong tree
Wasting your energy by going on the wrong path, to make the wrong choice, to have a wrong idea
He got cold feet
He got nervous and changed his mind
Give it a shot
Try something, give something a try
By the skin of your teeth
Barely escaped or achieved something
I’m in the same boat as you
In the same situation as someone else
It came out of the blue
It came out of nowhere
I’m drawing a blank
I can’t remember right now
