a situation that causes a lot of problems for you when you start to deal with it
a can of worms
to make a hasty conclusion about something or someone judging only by its appearance
to judge a book by its cover
to make an argument or a bad situation even worse
to add insult to injury
when something is turned around from the normal position or orientation
back-to-front
to avoid talking about what is important
to beat around the bush
something that seems bad or unlucky at first, but results in something good happening later
a blessing in disguise
completely opposite
poles apart
very calm or very calmly, especially when this is surprising
As cool as a cucumber
an easy and happy existence
a bed of roses
something that is very easy to do
a piece of cake
