Majority of my classes are boring too. Even if I wanted to talk in them, the rest of the class decide to be dedicated students, meaning the teacher's voice gets precedence over mine. I always end up dozing, and if I don't pull out a pad of paper and start jotting down anything, I'll almost definitely fall asleep. I make sure to sit at the back just in case that happens. Otherwise, I find I could come up with some pretty interesting drawings during class.
Watering plants is pretty fun! Since I was a kid, I've always had some sort of admiration for the hosepipe. Whenever my parents would ask us to wash the car, I'd take the job of hosing it down in an instant. It beats scrubbing on the outside or vacuuming the insides. I also find hosing down people a fun experience too. You probably shouldn't trust me with a hose. :P
