Animals
So hungry I could eat a horse
really hungry
tough nut to crack
a difficult problem
feeling blue
sad
Easy as pie
something that's easy
they are two peas in a pod
friends that are a lot alike
he's blind as a bat
someone who can't see very well
bigger fish to fry
more important things to do
she has butterflies in her stomach
she's nervous
Going bananas
to hit it off
find yourself immediately or naturally friendly with someone
smell a rat
detect something suspicious
take it with a grain of salt
be skeptical
he's bored stiff
he's really bored
A piece of cake
something easy
a shoulder to cry on
someone who listens to your problems
let the cat out of the bag
tell a secret
a baker's dozen
13
I had a change of heart
changed one's mind
he's nuts
someone is crazy
they are thick as thieves
very close
kill two birds with one stone
achieve two goals at once
she got egg on her fact
embarrassed
let one's hair down
relax
She's a fruitcake
someone who is really strange or crazy
bury the hatchet
end a conflict
