until the cows came home

to be in his shoes

to open a whole new can of worms

to burn bridges

at the drop of a hat

to knock her socks off

to jump ship

to sweep it under the rug.

got the short end of the stick

Miss the boat

It's not rocket science

Speak of the devil

Pull yourself together
