I'm assuming his aunts sister is older. Obviously some people have lives and leave their houses but you'd be surprised how many people that live in florida, don't leave their houses much, even in the pleasant winter months. Most people (atleast on the gulf side/tampa, fort myers) have pools, nice screened in lanai's and don't have a need to leave the house. Younger people have migrated down there but a lot have left as they realized it's not as desirable as it was during covid. Most older people just stay at home, regardless of weather. I lived in austin for a year. While it's hot, there's still tons to do outside. Definitely beats artic air.
