The Acting was phenomenal. The film reveals the reality of the struggle to be a responsible parent, have a career with a husband who gives little emotional or physical support to nurture her or their family. Her obsession with the young mother, ;impatient and unable to give her girls the attention they need, unfaithful and scatter minded about what she needs- adds complexity to the universal issues of parenting. Olivia Coleman sees in the young mother her own inadequacies to deal with motherhood, emotional attachments and a fulfilling career.The orange 🍊 seems to me to symbolize the delight and fulfilment the children crave from their mothers, that is, the attention and sweetness of sharing the art of peeling the orange with the time and attention it takes to wind the peel like a snake without breaking it).
