Same for my Grandma. She was 79 when Grandpa died, and she lived to be 94. She sold the farm, moved to town, started wearing pants (!!) bought a little go-cart to drive around the neighborhood in... I mean, she cared about him, but he'd been a drinker, and she was very straight-laced. She was appropriately subdued for 2-3 months after he died. But after that, it was pants and the go-cart, and all smiles. LOL! And she said she'd never, ever marry or "go with" a man again. And she didn't. Any of the old fellows in the community who expressed an interest were shot down with withering scorn.
She wore pants after her husband died?! 😳😱 Mom never got THAT brave. (Dad was a Baptist preacher, only skirts.) But she did turn into a hussy and wear ... EARRINGS!
She was forbidden to drive, but when she was 80, my aunt secretly taught her to drive, and took her to get her license. She was 84 when Dad died, and the day after the funeral my sister and I bought her a car. She was so proud of that car. The farthest she drove was about 10 miles to work.
