When my wife was breastfeeding, I was told my grandfather was quite old fashioned in his views on breastfeeding (it should be done in private. At a family gathering, my wife went off to another room, to not make him feel uncomfortable. Shortly afterwards, we realised my grandfather had noticed she was missing, and went to keep her company. He would rather feel uncomfortable himself than let my wife feel pushed out. (He was completely unaware of the previous discussions)
