Add fuel to the fire
Making something worse
Let the cat out of the bag
Reveal a secret
On cloud nine
Very happy
Crocodile tears
Fake crying or not really upset
Smart cookie
Very smart or wise
Hit the sack
Go to bed
The apple of my eye
Someone's favorite
Kill two birds with one stone
Achieve two things at once
Break the ice
Relieve the tension
Two peas in a pod
Just alike or the same
Spill the beans
Reveal a secret
Piece of cake
Easy to do
Needle in a haystack
Look for something almost impossible to find
Time flies
Goes by quickly
Wolf in sheep's clothing
A trickster
Raining cats and dogs
Raining very hard
