My college senior seminar thesis that would’ve become my honors thesis (if I took the ‘nother course of research and review meant to prove me for grad school) was about the split-level house

My take was it was kind of about how less grimy heating made basement rooms practical

And kinda about how adults wanted separation from their dumb boomer kids

But mostly about how WWII trained a generation of men in dozer-concrete retaining wall construction and that rendered more marginally sloped plots viable
