FWIW, I can cook, clean and take care of myself in the absence of a wife and have done so on numerous occasions when my wife has been out of town for extended times to care for an elderly relative or a daughter who just gave birth.
I love my wife dearly, but sometimes I actually look forward to these absences because I can cook what I want, when I want it, open the sardines and get the deer sausage out of the freezer to fry up without anybody complaining. I can also turn down the heat to 55 degrees or so where I am most comfortable and leave the toilet seat up.
I suspect there are a lot of menfolk in exactly the same situation.
Oh, no, now that I understand, except that it's my Teutonic bride that likes it cold. My ancestors lived in much warmer climates. I'm positive that's the explanation.
