Am I the only one...

...who thinks it's strange that dogs eat whatever is put in front of them, as if the entire world is their own gigantic food bowl? I just watched my dog stick her face into my carry-on bag until she found the one piece of popcorn that had fallen in there, and then proceed to eat the piece of popcorn without regard for whether or not it was in fact ok that she eat it. What is that about? Why do they do that? So selfish.
