Here’s an essay about a 25-year-old who suddenly gets a new half-sibling. Yeah, I identified a little bit. “The mathematics of a post-nuclear family is a bit stunning. When my [brother] enters kindergarten I will be entering my 30s. When [he] goes to prom I’ll be a soccer mom. By the time [he] is legal to drink, I’ll probably just be coming out of rehab myself. When I’m 50, [he]’ll be 25, the age I was when [he] was born. We weren’t [siblings]; we were victims of circumstance.” (Link courtesy of John.)
