• none the wiser

• it's an ill wind that blows nobody any good

• be wise to it

• a white lie

• have one's wires crossed

• worth his while

• a white elephant

• put the wind up him

• see how way the wind blows

• a stupid wise thing to do

• blue-eyed boy

• as white as a sheet

• see which way the wind blows

• lightning never strikes in the same place twice

• eyeball to eyeball

• any which way the wind blows

• strike while than one string to one's bow

• take the wind out of his sails

• sow one's wild oats

• be wise after the event

• in black and white

• in the wind

• a live wire

• wipe it out

• get one's second wind

• live wire

• give a wide berth

• wild horses couldn't drag me there

• raise the wind

• cast pearls before swine

• while there's life there's hope
