A chair is an object specifically designed and created to support the weight of a human while they relax, rest, wait, or work. In all caes that chair represents space specific to the occupyier of that char. Hence you will often here….“HEY!....That’s MY chair!! You are sitting in MY chair!!”
So no matter who owns the chair it momentarily becomes the property of the occupier and in many cases a defensible proposition easily domonstrated at any large family gathering. A chair can also serve as a tamer of chaos where a person who is nervous, aggitated, resistant or combative suddenly becomes calm, cooperative even complacent when place in a chair.
So at times a chair is many things and the bulk majority is it mere decoration waiting for that next time a weary soul sits down to eat, work, rest, watch tv, play a game, or wait in the waiting room for the next appointment. No other item created by man serves one purpose for so many reasons.
