When Did 9:30 PM Become Bedtime?

When you're working, evening is the time that you watch TV, surf the Web, check your email, update the task list and try to do a little work.  You know, just enough work to take the edge off the next day. Get ahead, which really means getting a little less behind.  Get in the last word at work the night before to ruin someone else's morning.  Not being mean -- just the way it was.  Getting the edge, making the next morning more tolerable.  I had not realized that when you're not working, the distractions aren't distractions anymore. They're your retirement job.  It's 9:30 PM and I finished my evening chores. Feels like I should be able to keep going, but I've run out of "work" to do.  If I did any more today, I might not have anything to do tomorrow.   It's 9:30 PM -- bedtime, I think. Perhaps this is why an accepted definition of "retirement" is "going to bed (early)."  I didn't see that coming.
