Green
He's blowing his own horn
He's bragging about himself
He is down in the dumps
He's is feeling sad
It's dirt cheap
It's inexpensive
You need to stay on your toes
Pay attention, stay alert
His head is in the clouds
He is day dreaming
He's nuts about you
He really likes you
She has a heart of gold
She's a kind caring person
She put her foot in her mouth
She said something inappropriate
I'd like to sleep on it
I want to think about what you said
I feel like I'm walking on air
I'm very happy
He's studying
Don't throw in the towel
Don't give up so easily
He bit off more than he could chew
He trying to do more than he can handle
He's on top of the world
Hold your horses
Wait, be patient
