Just like real life. I don't know anyone with one of those screened off porches on the side or back of their house that's ever actually used except as storage.
We've got one at our cottage and if we're inside it's pretty much the default place to be because that's where we can see our yard from and it's where our stove is (not logical or our decision but whatever 🤷)
Dude I've been watching Family Guy lately and think about that every episode. I hadn't seen most of the seasons before and I keep thinking that one of these days they need to address it. Are they going to address it??
