I would say that the almost all of the people I've came across in my life have turned out to be acquaintances as, there is been an extremely small number of people whom were true & honorable friends, though lost contact with them etc. I'm not someone whom would go out of my way to track someone down to reestablish contact through Facebook or some other honorable means of such. The way I see it is, that I'd rather leave people to conduct their lives without any burdens, hindrances, problems, etc.
