Ocean waves in the moonlight
Like talking to a wall
cavity
Cast pearls before swine
A waste of time and effort
Serendipity
A snail's pace
A know-it-all
Bullshit
Birds of a feather flock together
magpie
Nuture over nature
To have second thoughts
To use cowardly tactics
To pull the strings
To talk behind someone's back
To trade a loser for a winner
thin; sparse
faint; ineffectual
to throb in pain
to crouch; to squat
