Dog park people

So what is it with people who bring their dog to the dog park, and then spend the entire time yakking on their cell phone instead of playing with their dog?

Dog park isn't supposed to be just another place to ignore your dog. It's supposed to be a place where they can go meet and play with other dogs and where you can go have fun playing with your dog and let them run around without worrying that they'll run out onto the street and get hit by a car or something.

Gotta wonder about some pet owners sometimes.
