This is a story about a man named Jed

Ok, so I actually met a guy whose sister is his wife. We'll call him Jed.

Jed is about 47 years old. Jed's mother died in a car crash when he was 15. Jed's father remarried a young widow when Jed was a grown man about seven years later.

Jed's new stepmother had a daughter who was about 17 when she became Jed's dad's stepdaughter. And she was about 24 when she became that same man's daughter-in-law.

Now Jed and his lovely bride live in a house they built next door to their parents and in-laws, who are one in the same. But unlike the shared driveway leading to the two houses, the family tree of Jed's children does not eventually fork in two different directions. At first glance anyway.
