We are only hearing one side (not saying that side is incorrect, only that it is one-side of the story). Maybe MIL is stressed by having too many family members for company who perhaps do not help out enough, and come in like princesses after all the wrok has been done, to sit down to a meal. Maybe Bubby is overwhelmed at having to be the de facto babysitter over yom tov (as SO OFTEN is the case when kids come for a Shabbos or yom tov and feel now they are free of parental responsibility). Maybe, MIL really should not have the company, but BE the company. Just something to consider as a possibility…
