I was reading a bunch of your posts and thinking about what really scares people about high school, and going to college, and going on to whatever follows. At last count I've moved 17 times, mostly from house to house in the same town, but I've lived in 4 states and about 6 different cities. And every time I moved I was afraid of the same things you described in your posts. I was afraid I wouldn't know who to eat lunch with, or that I'd end up having to fight someone, or that I'd be without some vital piece of information that every other kid in the new school or the new neighborhood had in their possession and I'd look like an idiot. I was convinced that I was some sort of weirdo and that I'd be alone.
It's weird how powerfully frightening that idea of being alone can be. Great pieces of art and literature are built on just that fear (Like Andrew Wyeth's "Christina's World" above). Think of George in
Of Mice and Men. Think of Dr Frankenstein creating his undead monster. The scariest of all movies are all based on being alone when the crap hits the fan. Boogeymen and serial killers fade into the forest or disappear into an alleyway when someone new walks into the scene.
One friend makes all the difference. A friend makes school an ice cream parlor when it used to be like a freezer full of unmarked leftovers. Having that person to share a look with, or decompress with after a tough test or a weird day banishes all of those lonely fears like music displaces silence. Three or four of you already alluded to this, that you sat with an old buddy then branched out as days and weeks rolled by. That's what life is - stepping out from that safe place that friends and family provide. Those little fears and frayed nerves disappear so fast.
