What keeps you up so late?

I don’t mean this metaphorically. I would like to know why you are up so much past midnight? What keeps you from sleeping? Do you even know?

I’m not sure I do. Yet, here I am, night after night, until 1, 2, 3, even 4 in the morning. And I get up at 7 the next day. I never could have done this when I was a teenager. I feel I shouldn’t do it now. But I hang out here, and I can’t go away. I need to have my say, I guess.
