Wrap your head around something
Understand something complicated
We'll cross that bridge when we come to it
Let's not talk about that problem right now
A penny for your thoughts
Tell me what you're thinking
A perfect storm
the worst possible situation
Add insult to injury
To make a bad situation worse
By the skin of your teeth
Just barely
It's a piece of cake
It's easy
It's raining cats and dogs
It's raining hard
Let the cat out of the bag
Give away a secret
Look before you leap
Take only calculated risks
On thin ice
On probation. If you make another mistake, there will be trouble.
Once in a blue moon
Rarely
Put something on ice
Put a project on hold
Rain on someone's parade
To spoil something
Take a rain check
Postpone a plan
The ball is in your court
It's your decision
