all ears
fully listening
break a leg
good-luck
cold feet
nervous just before a big event
cost an arm and a leg
be very expensive
(my) flesh and blood
relative
get something off one's chest
tell someone your problems
have one's head in the clouds
be unaware or unrealistic about something
head over heels
deeply in love
keep one's chin up
try to be cheerful
by heart
memorize
over my dead body
not unless I'm dead and can't stop you
pull one's leg
joke or tease someone
see eye to eye
agree
in the blink of an eye
extremely quickly
fingers crossed
hope for good luck
