An observation in 100 of fewer words:
In the most basic sense, there are two types of people in the world. Type One makes the bed faithfully every morning. By chance, if they ever noticed that their bed somehow remained unmade later in the day, they'd still be compelled to make it before sleeping in it -- even if they were going to bed in less than an hour.
Type Two does not and would not.
Inevitably, Type One's and Type Two's marry each other.
