What does it mean to have something? I'm suddenly getting that overwhelming feeling that comes from having loudly announced to a room that I have something significant to say. But neither of the "haves" in the previous sentence will do for the present purpose, although they too will have to be explained. I also say that I have a laptop. I think I mean that I count on being able to use it. Why should I make such a point of distinguishing using it from enjoying it? To answer that I'll have to say what "use" means.
That's all I've got today. You were expecting, what, a dissertation?
