“... I don’t mean to be critical, but your son must not have been very hungry”.
I think you missed her point, oh8eleven. She didn’t want her son to feel like he was poor or in need. She selflessly ate the crust of the bread for her lunch so that her son could eat the sandwich they way he preferred. I had a great Aunt who was extremely poor. She would tell her family that she didn’t like the taste of meat but did like the fat. What she was doing was leaving the good protein for the children while eating the fat for herself. It’s what a good Mom does.
Are we related? I had an aunt who did the same thing. :-)
