CNN has an article about a polyamorous "throuple", three gay men in a long term relationship. They engaged the services of one egg donor and two surrogates to produce children for them to raise.
They are described as a modern family unit.
Just ten years ago, I never could have imagined this configuration for a family unit. I wonder where we will be ten years from now. I guess we all reach the point where change comes too fast for us to process and we become "old". Maybe I'm there. No judgments, just a comment on how the longer I live, either the pace is picking up or I'm slowing down. Maybe both, I dunno.
