Two sisters A & B (now adult but 3yrs apart in age, A the older) grew up in a stable family & lived next door to Mr & Mrs Peach. Mr & Mrs Peach were barren and absolutely doted on A & B. They cut a hole in the garden fence and installed a gate so A & B could pop over any time they wanted. A & B often baked cakes with Mrs Peach in her kitchen. They tended the veg patch with Mr Peach. Often played rounders or badminton in the garden together. A & B accompanied the Peaches on dog walks /trips to the beach etc. All with the consent of A & B's parents. A & B became the surrogate kids the Peaches could never have. No funny business occurred, everyone was happy. Growing up, A & B moved away & had their own families and lost touch with the Peaches but always had fond memories. Move to the present day & A & B have both married and had their own families, although A is now divorced. Their parents are now dead. B gets a letter one day saying the Peaches have passed on and she alone has been named as the sole beneficiary of their entire (substantial) estate. B already having paid off her mortgage goes on a spending spree; all new windows & doors (including internal), new roof, a whole house worth of new furniture & decoration, new kitchen, front & rear gardens, driveway & new car. Then has two foreign holidays. B hasn't remotely suggested that she could share some of her good fortune with A. A is eaten up with jealousy. Jealousy at the great uplift in her sisters lifestyle & jealous hurt that her younger sister was clearly 'the favoured one' with the Peaches, which has now soured the memories of her youth. Is A right or wrong to be jealous? Is B right or wrong not to share? Both sisters are in their 60s now. I think this may be the end of their relationship.
A is my mother and she now has a massive chip on her shoulder.
