A faint hum in my life

You know how your ears ring after a long loud noise stops? Well, now that Falstaff's continuous-motion-machine is not in my life, there's this kind of a hum leftover -- I catch myself thinking suddenly, "What's he getting into?" or "How long has he been with Frank's mom today?" or I brace myself when the door opens, but it's only Frank and Sturmz, no explosion of wiggle and jump. I'm suspended between "whew" and "waahh."
