My dad went to the 6th grade and then into the Navy. He met my mom when he came home. He came from a poorer family. She was a bit spoiled and did graduate high school. I never wondered if my grandmother objected to him because he had not finished school. It didn't matter because he was so bright he could discuss almost any topic. He built a massive house with an apartment off the garage for my grandmother to live with us....convenient for child care and rides. Plus, she did all the housework and cooking. My mom liked to work and make money. Together they amassed millions. Then spent it in their retirement. $500,000 went to having my mom in assisted living for five years. They left a lot to my sister and me but not my other two siblings because they moved out of state. My dad thought that was terrible. So he punished them. We did a lot of work to take care of them before they died. My sibs just came for the funerals.
