Who are you Talking too?

In a recent Fred Basset comic strip, Fred is asleep on the floor and his master reading the paper in his chair nearby, when a voice from afar says, “ Dinner – come and get it!” In the next panel, both Fred and his master simply look at each other with a quizzical look on their faces. And in the final panel, they both turn towards the unseen voice and say, “Me or him?”
This led me to ponder on how well we actually communicate with others? Are we as accurate in doing this as we think? In other words, do we do it clearly, so that there is no doubt as to who is being referred to? Or do we simply do it in a generic or lazy fashion like in this comic strip; so that there is confusion in everyone’s mind as to whom, if any, you are actually talking to?
Again just something to think about when communicating with others, whether dogs, cats, or people!
