Animals
Raining cats and dogs
It's pouring rain
Beat around the bush
Talk about something but don't get to the main point.
I'm all ears
I'm listening intently/I'm ready to hear what you have to say
Hold your horses
Wait a minute. Don't be in such a hurry
Once in a blue moon
Cold shoulder
Won't hurt a fly
The person is very peaceful and non-violent
On cloud nine
To be extremely happy
Play it by ear
To do something without planning or preparing beforehand
Lion's share
The majority of something
Shoot the breeze
To have a casual conversation with someone
Turn the other cheek
Don’t retaliate when someone else has hurt you in some way.
Wild goose chase
To go after something you're not likely to get
The apple doesn't fall far from the tree
A person is similar to their parents
By the skin of your teeth
Barely manage to do something
