I'm searching the title from a German movie from the 70s - 80s. I saw just few minutes, all I remember is here.

German or Austrian movie from the 70s - 80s.

An extended family gathers for the weekend on a big house with a big garden. Everybody or almost is happy: children play, people cheers and many characters talk. The movie is simply a collection of some of the dialogues. In one scene a young guy is sitting serious without talking anybody. A woman slightly older sits beside, sees he is sad, and start to talk to him about a happy anecdote.

Is an idyll. Maybe it has other overnotes, but I saw only few minutes.
