11.30 = bedtime
Being a nightowl is awesome, cause you get lots of stuff done late at night. But you also end up like the living dead the next day, and I have a sneaking suspicion that I would be more productive in daylight if I stopped staying up late all the time.

(The irony is not lost on me that it's taken me a few more minutes past the 11.30 mark to create this non-amusing o'rly ya'rly owl image, which has consequently taken me past my planned bedtime.)
Goodnight.
