How Can We Efficiently Sort Socks with C#?

I'm an adult, most of the time. That means I have to do adult things, like getting groceries or gas or maintaining our yard. I am also married with three kids. And that means a LOT of laundry. Laundry by itself isn't too bad. It gives my easily-distracted brain a simple, repetitive task that often allows me to think more clearly than is otherwise possible. But the worst part of laundry, the absolute worst, is the socks.
