Maybe she was like my mother, who kept the same style she had in high school until the day she died. Of course, like all her family, shd had thinning hair, and I suppose she just didn't want to pay attention to it.
You know, the business of taking pictures of the dead is not all that odd. People did it up until fairly recently, if the person had not been recently photographed. It was sort of a method of rounding out the history of that person. I have a particularly gruesome one of one of my great auntie's husbands in which it is clear that he is dead, and has perhaps been dead for some time. Used to terrify me as a child, and I still don't like the damned thing.
