What does this painting tell you?

11. That there is an awkwardness between father and son.

The father doesn't know what advice to give the young man. Maybe he has served and remembers the horrors and wishes his son wasn't going there. The father is sad, the son is nervous and anxious to get going. Mom is absent, but represented by the bag lunch. It was too painful for her to say goodbye. The dog is the only one reaching out and showing any connection. She has her paw on his knee and is asking him to stay with her.

It is about the passage of time and leaving behind the old life and embarking on a new one.
