I don't think he was being a smart alec, but rather just talking on something with what he knew about it, in a subject where he really didn't know much about it at all. But that's the way it is with guns, I believe; unless when you are young you are actively involved with them, you are not going to know much about them unless it is through the experience of years.......especially when the current society feel on them but that could be beyond the subject.
Of course, the two classmates examples I am pulling on are both actors, so on the face of it, that could be a major difference there....but then again, I've been classmates with "them" for about 4 years so it is not entirely a contaminating process, if one follows my meaning. Not that I am chopping them down on that for that is one of the things that tears at me in that I can be in part of their world, but I cannot be entirely in that world.....I'm still what I was before I entered it.
But looking at some of the conversations I've had with them, such as with my Serena Complex, I suppose there is a tendency to believe what you know is sufficient and all encompassing.....when at this age it isn't and perhaps from the angle of the Serena Complex, perhaps even unimportant.
Wine, guns, what else might there be?
