Trott desiring his absence offers to do everything in his power to hasten his friend's departure, of course all for friendship's sake. Gilfen puts him to the test by pretending to need all sorts of things. He begs Trott to fetch a parcel lying at the custom-house, and weighing forty pounds; a letter from the post-office, a rose-tree for Louise, and a travelling-map, which was only to be had at a stationer's shop at a considerable distance.
Before leaving the house Trott finds an opportunity to tell Louise that he does all this for her sake only. Gilfen, finding him with his wife, sends him on his errands and then leaves Louise to herself. She is filled with sadness by her husband's indifference and sings a pretty song about a youth, who makes love to a maiden, and a man, who neglects his wife. Gilfen returns, attracted by the song, and guessing that his wife still loves him as before he decides to stay at home.
Louise leaves him and Trott returns out of breath and laden with parcels. The husband thanks him, but explains that there is still a letter to be written, for which an important document is needed, and is to be found in a chest on the next floor. Trott is hastening away, when Gilfen implies, that he must have the chest itself. Seeing the carriage, waiting outside Trott rushes away, determined to do his utmost for friendship's sake. Then Gilfen appears before his wife in travelling costume.—In the interview, which ensues, Louise shows him clearly, that her heart is still his, but that she longs for more tenderness and love. They are interrupted by Trott's entrance, dragging in the heavy chest. Gilfen declares that he has now everything he wants, and takes an affectionate farewell of his wife and his friend.
Left alone, the latter loses no time in making love to Louise, but all he gains is a friendly handshake. Mistaking her coolness for timidity, he becomes bolder. At this moment Gilfen re-enters, telling them, that his carriage has broken down. Trott hastens out, to see to its repair and leaves husband and wife alone.
Now Gilfen owns that the carriage is intact and that he only come back, because he felt, that he had left the best thing behind him. "What is it, that would keep you at home?" asks Louise. "A wife, who would plead with a smile: do not go," he answers.—
A pretty duet follows, in which they indulge in sweet reminiscences of the past, and at last discover, that they still love each other as fondly as ever. Embracing her husband Louise whispers smilingly: "Do not go!"
When Trott returns Gilfen astonishes him by telling him that he has decided to stay at home. Trott perceives at last that it is his turn to go. While he still lingers, he receives a note from Louise, showing him unmistakeably, that he is not wanted in their house. He retires crestfallen, while Louise and Gilfen gaily wave their hands to the departing friend.
