AHAHAHA, DINOSAURS
-Excuse me. You like dinosaurs. The very concept perplexes you. The idea of these HUGE creatures wandering about the earth several million years ago excites your mind. And the idea that they all ceased to exist so abruptly by meteor...
It's a shame you'll never meet a real dinosaur in real life. You'd love to ride on the back of a t-rex. Scaring all the other dinosaurs around. Shooting your fire breath at unsuspecting civilians. Flying above the cars, crushing them with your 93-million-mile stare. Dragon. That's what I'm saying you'd love to ride, a dragon. You don't know the difference between dragons and Dinosaurs.
Meowrage has attempted to explain the difference between the two, but you just ignore him, and favour your own imagination. It's more fun that way.
You picked this background a few years ago-not, you picked it 3 days ago. You thought this dinosaur image looked cooler than the one that you had back then. You still do. And you'd be willing to change the image as soon you come across an even cooler image. But as it stands, this one is here to stay.
