I like riding in the car with my humans, but when they leave me in the car and go into the store, I get a little worried.  I know they're going to come back, but I'm impatient.  I just stare out the window and watch the front door of the store.  I check everyone that walks out, "Not them....Not them...Not them...."  Sometimes I even start drooling profusely, which I don't normally do.  Then when I finally spot them, I get super excited and occasionally try to jump in the front seat when they get back in the car.  When my pack is all back together, I can settle down in the back seat and chew on a bone.  All is right with the world.
