If I were going outdoors, I'd put on at least 3 layers of clothes, plus my jacket, wool hat, and gloves. And indoors, I'd turn up the heater and cover myself in 1 or 2 blankets. Even though I live in Texas, I'm cold-natured.
I usually drag my mink blanket into the living room with the heater on, haha. But at the moment it's summer here and today was rather hot, I don't really want to be thinking about ways to keep warm, hahaha.
Fireplace! For sure! My mom says I'm like a cat that way... and, because in my apartment I don't have a fireplace, I stay under a pile of super fluffy blankets and refuse to leave my bed... exactly like my cats, lol!
