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