Mrs. Hillbilly Mom is about to declare herself nocturnal.
The sun has not been setting to my satisfaction. My evening walk is delayed later and later each night. For a couple more weeks, anyway. Lately, I have not started my driveway walk until after 8:10 p.m. By the time I come back in, snack the dogs, and fix my supper, it is after 9:00. Then I start on my "refreshed" 44 oz Diet Coke. Since it weakens throughout the afternoon as the ice melts, I shock it with a little bottle of Diet Coke and some more Great Value Cherry Limeade. I'd worry about the caffeine keeping me up, but...well...I stay up anyway.
Most nights I go to bed around 3:00 a.m., then get up at 9:00, run my errands, fritter away some computer time, fix supper for Farmer H, clean the kitchen, whip up two blog posts while I wait for the sun to edge toward the horizon, then head out for my walk. It works for me. I imagine my lifestyle will skew with the sunlight as the year slides towards Christmas time, in order to get my walk in during daylight hours.
Retirement really agrees with me. Farmer H, not so much.
