Two characters suffer each other's company for the sake of a third, actively quarreling when that third character leaves the room. Should they come back, everything is as it was with that third character none the wiser.

For instance, Alice, Bob and Charles are in a private space. Bob and Charles hate each other, but they both like Alice, and thus they act as though they like each other too. Alice has to leave the room for a minute and Bob and Charles are immediately trying to kill each other. This goes on, Alice deaf to the fight, only for her to walk in, none the wiser as Bob and Charles have already swept the broken vase under the couch and the table set upright again.
