Tie the knot
That was easy!
Feeling sick
Cat got your tongue
Under the weather
Hit the nail on the head
Cost an arm and a leg
To get married
Rarely
Piece of cake
Break a leg
Once in a blue moon
You got it!
Good luck!
Don't get upset over the little things
Seeing eye to eye
Don't cry over spilled milk
Cold shoulder
It was expensive!
Told a secret
To ignore someone
Let the cat out of the bag
I am speechless
Agree with someone
