an open letter

Dear God,
Why did you make fireflies? Do they serve a purpose? Or, is their purpose solely to amuse us homosapiens? (I know, can you believe someone was pompous enough to call your people-creations something so fancy?) Are they to entertain small children and give them an opportunity to learn the ill effects of trapping an organism in something that is not its natural habitat? And, why their butts? Why not their wings? Light-up butts are funny. Thank you for not giving me a light-up butt. And, is it voluntary or involuntary? Can they decide when and how frequently to light up their little behinds? It doesn't seem that they have control over the length of the illumination, though. So, why not? If it's involuntary, it seems a little cruel. It's hard to sneak around, in stealth bug mode when your ass keeps lighting up. But, maybe it's for their own safety. Your prompt reply is appreciated,
Hyla
