I do the same thing at this time of night.
Refresh BYC
answer vaguely interesting posts (doesn't really have to be THAT interesting at this hour either)
pat the kitty on my lap
check Facebook
kick the kitty off my lap
get a beverage
check for new posts (write something absurd, preferably to Boyd who's usually equally weird at this hour)
apologize to my kitty (who has now returned and wants me to come to bed)
look at the clock and sigh
refresh BYC (telling myself it's the last time and then I'm REALLY going to bed this time)
realize I can't get up now because the kitty is comfortable again
etc
etc
Too lazy at this hour to do much else. It's my wind down time, but it does get a bit redundant. Oh well. Always been a night owl, I can't help it.
