Well, dangit, it's hard to get real dirt out of their wingtips...and loafers load up easy in a plowed field.
@Smokin JoeConsider the moving in and out of this place - NASA
I worked at a middle school doing my usual counselor/testing/managing special programs, just a few blocks off NASA One highway in Webster town - that highway took you a few miles from the school to NASA. NASA engineers came and went with children in my school; astronauts' children came and went in my school. Our school nurse whose office was across the hall from mine, was the wife of an astronaut.
I knew how minds of engineers/astronauts work. I knew I had such a person registering a child if the form they filled out was like this: Not one question blank was empty - every single one was filled out completely. If the question didn't concern the engineer person, he put an "NA". When I had such a person, I would say, "How long have you been an engineer?" The person would say, "How do you know I am an engineer?" Then, I would ask him, "How do you store your socks?" True engineers' sock drawer is supremely orderly. He then realized how orderly he was that told me he was an engineer.
Their children were bright even though they had moved around the country with the children changing schools frequently. I did the best I could to help them feel "included" with other students.
NASA is a place of "people" and they have "children" and they tend to move in and move out rather than having a fixed place to grow up. I was born in a small place in the east Texas Oil Field and stayed in that house until I graduated from high school and entered a college away from there.
