I had a sheltered upbringing too, sans father, my granddad being the head of our household. He wasn't domineering though, just conservative and probably thought he was shielding us from the harsh realities of life. He was a loving stand in dad, never raised his voice, patient and caring. We felt cherished by the three adults who raised us. I sometimes think what my grandparents must have gone through at that time when their eldest daughter (my mother) arrived on their doorstep in the early 1950s with three small children in tow. We were stigmatised at school for coming from "a broken home" but despite that, my upbringing was indeed sheltered.
I remember being really shocked when I first found out about abortions and I think I must have been in my late teens. I had never been to a hotel until I started working, at around 19. Didn't know about alcohol, there was one bottle of sherry in our house which would be brought out at New Year for the grown ups, who would have one small glass each. And then it would be put away for next year! I had a lot to learn.
