Being born there, living your entire life there, your whole family and all your friends are there, you went to high school and college there so it's easier to transfer to a CSU for grad school, and cheaper because you won't have to pay non-resident fees, etc etc. The same reason people don't move from other places. Besides, it takes a lot of savings to move, especially out of state, especially when you have to keep going back and forth to look at places. There's also just not wanting to move. I am really not ok with being forced out of my home and away from my family because of bullshit like this.
And yes the weather really is that good - in Southern California.
Self aggrandizing people being gossipy and passive aggressive...sounds like grad school.
