Many years ago when I was single, it was most nights. Since I’ve been married however, given that my wife loves to cook, and since she’s quite a bit better at it than I am, it’s not often. And that’s a good thing.
I fix dinner every day. And if you ask my kids if they wanted (in olden days) Mom or Dad to cook, they’d say Dad. Not that I’m a great cook, but she’s terrible at it!
