quiver worn on right hip

Repeated demands

A quack chooses gullible patients

Suddenly; Out of nowhere

selfish; stingy

A diamond in the rough

A pointless endeavor

You can't judge a book by its cover

Keep troublemakers on a tight leash

To poke the hornet's nest

porcupine

① A disease turned fatal ② A situation grown out of control

A healthy body begins with a healthy mind

Watch what you eat and what you say

To see the mountaintop

guilt-ridden

The mountain is not revered simply because it is tall

Children liven up the home

To make a careless error

To count your chickens before they hatch

It's all the same in the end

① Keep your lies reasonable ② There is no content bigger than its container

To speculate; To take a gamble

A shot in the dark

① Indistinguishable ② Unremarkable
