Anyway, yesterday I found out that those guys were civil engineers. I didn't even know that.
Here I've been married to a civil engineer for nearly 4 years and I had no idea that my husband was one of those who had to do all that embarrassing surveying crud on his university campus while everybody walked by making fun of him in their minds (high school kids make fun of people overtly while university types make fun of people in their minds or under their breath or in general statements on facebook).
And you want to know how I found out about my husband knowing how to take all those very "serious" measurements? He made me help him. On Saturday he calls me outside during the boys' naptime, hands me this enormous rod, and orders me to carry it to various parts of the yard, use a level to make sure I'm holding it perfectly straight, and stand there like a dork while he looks at the rod through a spyglass on a tripod and writes down decimal numbers that apparently mean something to him about the layout of our yard.
And people were driving by.
How embarrassing. And I know they were feeling sorry for us because we looked so dumb. But at least now my sweet husband can design retaining walls for our yard which is like a dream come true for him. I guess looking like a dork for 20 minutes wasn't so bad.
