Ahh yes, you grew up in a west coast subdivision. I am assuming either a late 60s to early 80s split level or a slightly more upscale true two story neighborhood, where every house is one of either two models, or a mirror image of those models to create the illusion of variation.
It is always funny, the first time you go to a friend’s house and use the bathroom, their mom will offer to show you, but you would just be like, “I know where it is.”
