Got Caught Daydreaming in Class Again

Professor Johnson caught me spacing out today during her lecture on thermodynamics. I was staring at a poster of Jupiter and had to come up with an excuse fast. Told her it's just the way Earth looks from space on that poster that fascinates me, but she gave me a disbelieving look. Now I feel guilty every time I see posters around campus since I know they remind me of daydreaming more than anything else.
