Elderly grandmother said to my sister “Wow, You have piled on the pounds.” Sister was secretly devastated as was said in front of her partner but they didn’t say anything and carried on as normal. When they left the house though she burst into tears. Sister now saying she doesn’t want to see grandparents anymore and other members of the family feel that the grandmother shouldn’t be told how much it upset her granddaughter as it will cause a big family row. I too feel very annoyed and upset for my sister but not sure how to approach it.
