Lucy Mangan feels she avoids responsibility whenever possible. She has cats instead of dogs because she can't face a needy pet; she only has one child which is 'more than enough'. But she's always been fascinated by those who run towards responsibility rather than away from it. She talks to Bea Harvie, a post-graduate student, whose father got ill when she was thirteen. Bea chose to take on a lot of caring duties towards her younger siblings while her Mother was busy caring for her Father. She describes the experience as something she just got on with, and reveals that it also was a useful distraction from dealing with her own feelings about her Dad's illness. Until one day when she was sixteen and it all caught up with her. She says its like shaking up a bottle of fizzy pop: ' it's got to come out some way.'.
