I think if I could have my home smell like anything all the time, I would want it to be fresh baked bread. There's just something soothing about it, and I don't think I'm alone in that.
Would I get tired of it? Maybe, I don't know. I guess it happens, right? But I'd be willing to give it a try. Better than coming home to the scent of litter boxes every day! And gravy would probably be the next best thing.
