I happen to have a sister who remains unmarried at the age of 52. She has told me that she probably will never marry. She had two loves in her life who didn't work out, and she has become used to doing things on her own time schedule, without having to consider someone else. She has a lot of nieces and nephews (and now my grandchildren) which she devotes a lot of time to, and she has a very well-treated dog.
She is happy and busy with her work. She is not odd at all, and has a lot of friends.
Since Harriet Miers comes from a large family to whom she is close, I imagine she decided staying single would be easier, especially with the career path she set out. All of this touchy-feely stuff would not be written if she were a man, by the way.
Thanks, I figured it was an undercut move.
Not to mention taking care of her 93 year old mother.
