before i go into my theory (doing lots of self examination these days) let me ask you this
you say it was crap for thirty years, then truly you must have felt this in your growing up.
was/is your mom a very strong individual? when i say strong i mean almost in a women's lib sort of way. not that she would have been part of the burning bra's era, but that she could do anything on her own, that she didn't need a man? when you look back on this, was your mom a typcial housewife (stay at home) or did she have a career or what?
