I mean, I would like to walk across the street and do some damage to the faceless, spineless people. But. They won't answer the door. I guess its ok to steal your neighbors identity but not to have the common curtesy to answer the door. Maybe they didn't answer because my dog was at their door literally waiting for them to open it. This is the dog who literally LOVES EVERYONE!!! But he sees my neighbors out in their yard and freaks out every time and shows aggression by kicking up grass and dirt.
