Keep a straight face
remain serious and not give in to the urge to laugh
to call a truce
to agree to stop fighting for a short period of time
hold one’s peace
to remain silent of refrain from speaking
peace and quiet
a state of calmness and silence
get in someone’s face
to confront or challenge someone
face the music
be confronted with the unpleasant consequences of one’s action
get the lion’s share
get the greatest percentage
let the cat out of the bag
to reveal a secret or disclose information that was supposed to be kept confidential
