Be up in the air
In the heat of the moment
Kill two birds with one stone
Take with a grain of salt
Crunch time
Give the benefit of the doubt
Can’t judge a book by this cover
Bite off more than you can chew
Blessing in disguise
Let the cat out of the bag
Lose your touch
Get out of the hand
Once in a blue moon
Best of both worlds
Stab someone in the back
Beat around the bush
Sit tight
Rule of thumb
