like a bear with a sore head | | |
like a cat on hot bricks | | |
like looking for a needle in a haystack | | |
to make a mountain out of a molehill | | |
to turn over a new leaf | | |
to call a spade a spade | | |
it's no use crying over spilt milk | | |
to have several irons in the fire | | |
to ring a bell | | |
to kill two birds with one stone | | |
