I'm an introvert. I spend a lot of time inside my head, just thinking about random stuff. Introverts think about more than just being introverts. :)
I make comics about those thoughts. That's why all my comics play out as thought bubbles inside the little yellow dude's head, and the outside world (the background in the comic) is irrelevant.
At least that's what I tell people when they ask me why I'm too lazy to draw a new background for each comic.
Anyway, if you're an introvert as well, you probably spend a lot of time inside your head too, and you also think random thoughts like the ones in this little book.
