My theory is that most non-English speaking people here in the States use the same system as dogs and children. They understand you when it is to their advantage. Actually, I believe that pets, who have nothing else to do than lay around listening to human conversation and observing the actions of humans really understand every word we speak. They are too smart to let us know it. If we knew our pets could understand everything we say, we would expect them to do more chores than merely bringing slippers and papers. They see the results of children becoming "intelligent".
