It has unfortunately been many years since I last saw Nate (well, always Nathan to me) but such is the way of things for out-of-state cousins, especially once everyone gets to the age where "summer vacation" is replaced by "summer jobs" and there are all sorts of seemingly more important things to do. On the other hand, not so much time has passed that childhood memories have been forgotten yet, from back when grown-up worries were the last things on our minds.
RIP, Nathan - nothing more to worry about.
