TELL ME WHY WE DO THIS?!!!!!

I was just wondering last night why I do this too. While I was out last evening, my dog decided to chew up the title of a car that I had sitting out on the table that I basically have sold. of course it's a 50 plus year old car to which I have a title from another state in another name so I can not apply for another title for the car. I have the pieces of it, most of them anyway, but not sure what I can do with it. The dog might as well been chewing up hundred dollar bills. For that matter, why do I have a dog?
