Paddy O'Connell has taken over the One to One interviewer's microphone to explore a subject that reflects his own experience: the effect of great emotional upheaval on family life.
Paddy lost his father when he was 11, and in last week's programme he met Sir Al Aynsley-Green whose career was shaped by the early loss of his own father.
This week's programme takes a slightly different tack as Paddy meets Lisa Cherry, whose childhood was spent in the Care System.
Born in a home for unmarried mothers, her childhood was spent moving from foster home to care home and a spell of homelessness. Eventually Lisa managed to get control of her spiralling life - giving up drinking and getting an education was the making of her.
