Title translation
This one may work, but a more accurate translation would be The Other's Son.
Inside every older person is a younger person wondering what the Hell happened!
If you are looking for the most accurate translation it should be: "The other woman's son".
share"The son from the other side" would be the most accurate translation, I think. But it sounds clumsier than just "The other son".
