Sam might try to portray this life of living in Surrey, mixing in different circles, like she’s better than what her life used to be, but deep down I reckon she must be envious of the life Billie leads. Married to Greg who is quite open with how much he fancies Billie and does his bit to support her to look after the kids whilst she works owning their own him with another being renovated, still in touch with all her long term friends, quite a steady career (not stupid ideas above her station like Sam has). Even Nelly and Arthur are naturally in to the hobbies that Sam tried to force her children into… I know which life I would be rather be leading
