to be a cold fish have a heart of gold as hard as nails. dresses to kill sth fits sb like a glove pull her/his stocks up. to be in sb's shoes to be sick and tired to be scared stiff. to be over the moon look down in the dumps to be worn out. can't belive your eyes give sb a hand put your foot in it. pulling sb's leg on the tip of my tongue get cold feet. get butterflies in my stomach break sb's heart can't get sth out of my head. learn sth by heart get sth off my chest to have a good ear for music. to be out of true to blow your own trumpet to face the music. to be music for sb's ears bits and pieces now and again. down and out give and take ups and downs. law and order safe and sound hustle and bustle.
