I think that someone can be affected by somethings in their earlier life that can affect them forever. I'm not talk about repressed memories, I'm talking about the lack of positively formative experiences at critical moments of their life.

Example - what happens when say someone starts school or is a teenager at the same time their mother is undergoing menopause and their father has lost their job and they're both starting to drink? The child will feel a lack of something but not sure what. If they do think of it all, they'll think of it as partly their fault.
