@contrex,
Ye... It's a tough one.
But as far as Joe is concerned, he has an automobile... At least, that's how he sees it when he's in his house looking at the car in the driveway.
But what about when he is driving? Isn't then the automobile an extension of himself? Then, for all practical purposes, Joe thinks of himself and the car as one unit.
But when I wrote the initial post I was thinking along the lines of how we see ourselves. How we define ourselves.
And in painting a picture of our own identity, everything goes into it. What you are (as you think of it to yourself) is closely linked to what you have.
You are a millionare because you have a lot of money.
You are an alcoholic because you have a drinking problem.
See? In some cases having and being are just two sides of the same coin...
