If you have not seen Harold and Maude...please do. Goth before Goth existed. All that needs to back my statement is Harold gets a new black 60's Jaguar; he chops it into a pimpin' hearse. I had a neighbor like Maude who Snowbirded to New Mexico in the Winter from Ohio.
My all time favorite elderly friend was,a woman named Victorene Jordan. She was born in 1898 and died in 1995. She told me ALL about the nuances of life and how it changed; things like the smell of horse shit in the streets before cars and the men on stilts lighting the gas city street lights and how the torch they used reeked of various unpleasant things that would do the trick.
What fascinated and still fascinates me is seeing the world through other people's perspective. I have found that the intentionally homeless tend to be the richest folks I have ever met.
