Good morning,

Forgive me please for future mistakes in my following description, I’m not english speaker.

Well, since some days a scene of a movie I saw long time ago obsess me and with the lack of information I got, I can’t find it. Here is the only things I remember :
It is a black and white movie and during a scene an adult explain the meaning of the life using a bottle and water. I am assuming it’s a son with his father, they are close to a river, sit on a wooden poonton.

I know these are minimal clues but it is all I can remember, so I hope somebody else has already see that movie and remember this scene.
Thanks you for reading.
