Mark, “uninvited guest” say a lot about how regard guests:-) Being able with birth control to “decide” to have children and it’s still a crazy optimism to walk into something you secretly know will challenge every attempt to be in control you can think of.
My older daughter studied Criminology and was told she was too curious about how crime worked so she switched writing insurance policies and doing risk management assessments. Many things happen that are predictable if you understand humans well enough. Younger daughter works contract in water resources and management for the city of Edmonton plus designs and delivers waste-management courses for all of Alberta. She was told “girls are no good at math and the sciences.” Lucky for him my more reasonable wife was able to correct him first.
Seems there’s a very unpredictable science in judging how people will turn out.
