Laziness

What's up with Sabrina? She's been clinging onto me since the other day. Anyway, I've been feeling lazy these days. I don't really know why. I don't think I'm sick. Sick of life? I don't know. And I know that instead of lazing around, I should be studying. It's kinda weird 'cause Mercurians are really industrious. We're not the lazy kinda, so why am I feeling out of it? UGH! Even Saki persuading me to study in military style isn't working for me. What's wrong?
