She always serves up massive portions for everyone else but only gives herself a small portion, if we have a chippy she only wants "a handful of chips", she always bakes but never eats it herself, she always encourages everyone to have dessert but never has it herself.
Is she trying to make us all fat?! For context, she is slim and has never had problems with her weight. FIL lost a lot of weight recently by cutting down on puddings, cakes etc as his cholesterol was getting high.
