I think the assumption of what is and isn't pampering is half the issue. Some people like some things, others don't. My ex-German teacher used to get her nails done every Friday night, she wasn't especially 'makeuppy' but it was something she liked to do after a long week at work.

I also like the long hot bath, good books and chocolate (cake too)! I also take my hearing aid out for the best part of the day as a form of pampering. The quiet is nice!
