I don’t remember my parents arguing, like being loud, but they did discuss things that sometimes sounded like an argument. They never yelled at one another, but my dad being military, didn’t hold back if I would sometimes try him.
I remember when my mom wanted to buy a dish washer and wanted it installed. My dad wanted to buy just a portable washer on wheels, instead of having it installed. This went on for probably a month. My grandfather settled it by having a new dishwasher delivered and my dad, being a pretty darn good carpenter, put in a new kitchen. My dad wasn’t happy that grandpa, his dad, bought the new dishwasher. I think that’s why he didn’t want a dishwasher installed.
