To answer your original question more in the way you answered mine, let me think. And I think, maybe the shallowness of my first answer may be a sign of someone who has moved a lot. There can be a reluctance to really open up and make ties. Maybe someone else can comment on this, too.
At least for me, once I hit my teens, I learned to overcome my natural geeky introversion and make friends. But, I never tried really hard to make them really strong friendships, somewhere in the back of my mind, I always new it wouldn't last. For ever was about 18 months, or 2 years. The rest of my life, never entered the picture. That was something that would happen in the future, someday, if I was lucky.
I think I have been lucky. Now, I can think of "here for the rest of my life." It just isn't where I ever thought it would be.
I guess that "shallow friend" making ability has helped me as a teacher. I can work with students be friendly and make attachments and not worry that I may never see them again.
I have made many good friends over the years, but because I never really made the effort to make those friendships deep, I don't have contact with any of them. The closest I have with a couple of them from college is a facebook friend connection. And I rarely spend time on there or communicate because our lives have gone in such different directions that we have little in common anymore.
Sounds sad and lonely doesn't it. It's not really. I have what is important to me. My wife and son. I have co-workers I can talk to. Students I can goof around with. And, you guys. I really don't have time for much else, even if such people were available.
So, in a way, I envy you and the ties you have. I think I could find some comfort in knowing that "this place is mine."
On the other hand, having moved around so much, I have met so many different kinds of people. Some were really cool, some very not cool, some interesting, some boring. That's a good thing, too, I think.
