Yep, my Depression-era parents thought any display of wealth was bad manners. I shop at Walmart and Sears, never go to restaurants, and travel on the cheap. Cars are a bit of an exception because of how unpleasant driving is around here and how much of it I do. My father would be horrified if he saw the Lexus. It fits like a glove and I'm not sorry from the comfort perspective, but I don't like the attention it draws. Will be stepping down in car with the next purchase in 5-8 years.
People that know me know I own rentals, but I don't think that translates into accurate estimates of my net worth. They know I retired early, and figure I'm getting a pension.
