I think, as you get older, you begin to separate the important things from those that really don't matter. I do not 'do' shoes, make-up, clothes or any other of the myriad things that some women just have to have. Anything I do want that's more than necessary (like that Kindle I keep banging on about), I buy for myself.
Yes, I do drive a sports car - a fifteen-year old MR2 that he probably wanted more than I did - and I do love it but honestly, I'd be quite happy with something less glamorous. As it is, I put most of the petrol in and pay the larger part of any repair bills (because I'm the one who uses it the most), but he insures and taxes it.
No, I wouldn't say I'm high-mainentance.
