deconstruction

So for our assignment I decided to deconstruct my friend dave picou. Daves a really smart guy so I figured he would be a good target to try this on. So I waited for him to say something. He began saying something about warcraft 3 so I jumped in. What is warcraft 3? he looked somewhat confused and then said its an online game where you choose a race and build up your forces to try and take over the other players bases. I said what is a game? He looked even more confused now and said a game is a competition between 2 or more people. This continued until he finally had to use the dredded word thing in one definition. Then I explained to him how our language is based on a series of assumption and abstract ideas. He thought about it for a moment then said, "So if the breakdown of every word is reduced to the word thing, the any word can mean anything and therefore us discussing this 1 makes no sense and 2 serves no purpose. We could replace any of our words with any other word and essetially it would have the same meaning." Daves a genious.
