We rented till I was ten, when my parents literally bought a house just around the corner from the rental. All the houses in the neighborhood were relatively similar in size and condition, and when young just assumed that was how the whole world was. I also don’t recall any relatives, grammar school classmates, or family friends being that much different off either.
As I got older and saw more of the world and had high school classmates with houses from “the other side of the tracks”, I realized not everyone had the same type of house. But there didn’t seem to be as much of a desire/need back then to have big, fancy houses. You kind of accepted what you had and made the best of it.
I don’t recall feeling embarrassed by the house, though I guess today one might have. But it was always my home, a stable, safe environment to grow up in, where we had lots of family gatherings and fond memories. And I was never embarrassed about that and actually still grateful for it to this day.
