Ralphie isn’t a real dog!

I’ve suspected it for a while, but today I finally saw proof that my roommates’ dog Ralphie is a space alien or robot or something.  The first indication was that when he plays with his stuffed animal squeaky toys, he is careful not to tug on them hard enough to damage them.  But the incontrovertible evidence is that while he barks at most cars that drive up to the house, he does NOT bark at the mailman.  Everyone knows that the mailman is a dog’s mortal enemy.

I’ll have to be careful not to let Ralphie see that I’ve caught on to the subterfuge, as I don’t want him to contact the mothership and have agents sent to erase my memory.
