Leaving aside the comments about waitresses, I can appreciate that. It is nice to get something new and actually use it, literally consuming it, so that everything about it becomes a part of you. Yet the same thing can happen to something that wasn't new, too. In a way it's nice to not have to worry about getting something scratched or a little dented. Either new or used, it seems to take a while before it becomes "yours."
Anyone that has been through the army knows about having things "for display purposes" and then having everything else for actual use. Of course in the army, you only get one firearm. One British writer that went through the Royal Military Academy and was then posted to an Indian Army regiment remarked that the soldiers in India, who regularly served on active duty on the Northwest Frontier, would never dream of doing the things to their rifles that the RMA cadets did to make them more presentable for inspection and on parade. Sort of the equivalent of the safe queens that are mentioned here now and then. I had long since given up ever being a serious collector when I realized that somehow or other my especially nice specimans collected scratches and fingerprints as much as the ones that weren't so nice. Never did figure out why that happened.
While it is also nice to inherit something for free, like an old gun, in your own eyes it is always someone else's gun, although you may not feel the same about that. But things like that seem to come loaded with obligations.
