Speaking of luxury, I have done some things to treat myself well:
During my tour of duty in Naples, Italy (1987-1992), I treated myself to a villa on a lake. It WAS a luxury...quite a bit above what was "comfortable" to spend, but more than worth it for the joy it brought me...the comfort...the blissful feeling of waking up to a gorgeous day on a lake with cool breezes and a screened verandah on which I'd take my various repasts during my off-duty time (which was, believe it or not, generous).
In my small condo, there are small pleasures....like luxurious bath sheets and fine linens for my bed. The true luxury, though, is the music and video that enters my life daily/weekly/monthly and the equipment on which it is played.
And then there is the theater, which is a luxury whether it's your life's ambition/vocation or simply a pleasure. I've treated myself to some splendid (and so-so) entertainments over the past few years.
And then there is this Sunday when I will see Leslie Jordan in his one-man show "Like A Dog on Linoleum".
