Watching on tv as little as I do, I didn't even know Manti Te'o had a girlfriend until yesterday (and when I heard his name on the radio I always heard it "Mann Taiteo"), but from what I've read today, if you get that attached to someone whom you have never met in person to the point of calling them your "girlfriend", then you're going to have all sorts of social problems if you make millions in the NFL.
By that reckoning, we're all boyfriend and girlfriend in the grand scheme of things. And we're all emotional two-, three-, and infinity-timers, too, I guess.
