To nap is to sleep lightly, especially during the day. I looked up the definition just to be sure.
Although a nap sounds like a lovely treat, I only nap when I no longer can walk; when I am almost falling down with fatigue.
I find “nap entry,” like re-entry into the atmosphere when on a space mission, problematic. Why is that? I’ll tell you. The reason I cannot nap is because of guilt; that dreadful quality of human nature, or more specifically female human nature.
