Weill im pretty sure it is an american film from late 70's to 90's not sure I watched it on tv like 10 years ago or so
It was a film about man who shared a little time with a guy who lived in a kind of trailer in the field or near a road and were near a factory or something like that where the first man worked, the thing is that the man Who worked there meet this guys and start coming for sharing time with the guy who was some kind of hippi or low life and lived with few resources and in one scene they ate cookies like oreos with milk and in a another scene the go for  walk in the field and eat tomatoes they found in the yard.
I just remember that. Also they became good friends and shared their stories and each one learned from the other's life or something like that.
