Well that's... a sad realization.
Don't get me wrong, I'll certainly live just fine with all that I have now, people and all, since I didn't exactly sit idly by all this time, I grew.
It's just sad that while at that time I would of cherished to be able to at the least talk to some of them one last time to at the least say a proper farewell (assuming everyone did go their different ways as I had always believed)... only for those feelings to perhaps not be mutual if what you say is true.
