“ I ask again, when was the last time you came
here and RandFan wasn’t actively posting?”
Exactly!
Some people have erratic sleeping schedules. I'm retired, and I sleep whenever I feel like it. I'm sometimes awake 20 or 21 hours, then I might sleep 5 hours or 12. I keep no regular hours. I can be asleep or awake any time day or night.
That's not uncommon among college kids, the unemployed, and the retired. Not universal, but not uncommon.
I don't know how old Rand Fan is, but if he's retired, an erratic sleeping schedule wouldn't be all that unusual.
