I think you’re close though not spot-on. We’ve had symptoms for years as we seem to be constantly improving our home, maybe partially fueled by HGTV but also fueled by having the time & money to finally upgrade our nest to be what we want it to be.
I think we are finally reaching a saturation point with HGTV home shows though….our consumption of them has trailed off dramatically the last six months. Not sure what we’ll end up watching with our after dinner wine now, though a combination of drifter antique collectors, storage vultures, and lard butt pawn shop shows have been filling the void until we find the Next Big Show.
