Ever waited for something that seemed done but wasn't? Like pulling bread out because it looks brown, only to find dough inside. Or when your computer says it's finished updating, but it's still doing stuff in the background for ten more minutes. That's probably what's happening with metal that's just cool to the touch. It feels ready, but it's still doing its own thing inside.

Watched my friend try to straighten her pictures before she gave up.

Cheap filters lol, I still get the fast food oil changed.

Twelve minutes with a book feels like a tiny vacation.

But what about animals getting in there? I've seen so many nests and even raccoons block a flue completely. Rain is another huge issue, water pouring down can really damage the liner and the fireplace box. Leaving it open just seems like asking for a draft and moisture problem down the road.
