confidence-building measure
Any action taken to eliminate or reduce the fear of attack or escalation of conflict between two or more parties, as in international politics, interpersonal communication, business interactions, etc. The term is usually pluralized. The two countries, long on the brink of all-out war, have introduced several confidence-building measures between their governments to facilitate better communication and hopefully avert the need for a military offensive by either side. One of our goals in marriage counseling is to create confidence-building measures between spouses, so that each person learns to communicate their frustrations before they turn into a source of conflict.
Elvis has left the building
Said when an event or performance has come to an end, or when someone or something has left a place, especially in a dramatic fashion. The phrase refers to an announcement famously made at the end of Elvis Presley concerts alerting people that he vacated the premises and no further encores would be played. We kept waiting for the band to come back on stage to perform some of the fans' favorite songs, but it looked like Elvis had left the building. That ball is flying, and it looks like... yes, it's a homerun! Elvis has left the building, folks!
