Personally, I consider family to be a social group more than a biological relationship. I have relatives that I’ve never met in my adult life that I don’t consider family. Conversely, there are people I consider family that were brought into my life through marriage, adoption, and close friendships.
The problem with statements like this is that they only ever seem to be made by narcissists who thinks work is only those efforts that directly benefit them. The end of my “work day” is when I start my other job of working for myself. I manage my home, I take care of my garden, I put effort into maintaining or improving my physical and mental well being, I foster and build the relationships in my life that I care about, etc. All of that is work, it’s just work that I do for myself and don’t get a paycheck for.
