Tip of the iceberg
Through the grapevine
Under the table
Throw a curve
That's the way the ball bounces
Tickled Pink
Tighten your belt
Up a creek without a paddle
Throw in the towel
Turn over a new leaf
Touch and go
Up against the wall
Turn the other cheek
Under the weather
Till the cows come home
In secret; dishonesty
To ignore something bad
In big double; in a difficult and desperate situation
To surprise someone in an unpleasant way
Rumors or gossip spread between people
Just a small part of a larger problem
To live on less money; to make sacrifices
For a long, long time
To be delighted; to be very amused or pleased
Very risky, uncertain
Sick; not feeling well
that's the way life is--we can't do anything about it
In deep trouble and can't do anything about it
To make a fresh start
To give up; to quit
