There are too many things about san francisco that make it such a wonderful city. But, there are also just as many things that make it suck:

the cost of living.
street folk.
overly-aggressive street folk.(I was robbed a month and a half in, and I've pulled my knife on two more people since then.)
loneliness.
traffic.
spit,piss,cum,shit,bile,puke,garbage infested sidewalks. Don't be fooled by the san francisco in the movies. It's a dirty fucking city.
loneliness. It's almost that feeling of walking down the halls of high school and almost running into that person who is walking straight towards you because neither of you know which direction to slide. Too me that's lonely because no matter what you will always laugh or be put out by that and it seems so lame to be rattled by but at the same time brought together with some stranger by something as lame and awkward as that.

shopping centers.
scientologists.
indian summers.
tourists
tourists
tourists
conventions.
starbucks.

There is a list equal to this that promotes all the great things about the city.

fog.
crisp days.
chinese food.
pizza.
cool style.
classic.
people I know well.
a job.
a fresh start.
a future I've always wanted.
inspiration.
I've never payed for internet in this city.
great indiemovies.
a space all my own.
great music stores.
illusions of grandeur
even the lists of bad things can go on here.(minus the street folk.)

I like it here.
