People have different reasons for living different places at different times in their lives, and eventually, they find “their place”–“their home.” That will happen for your daughter.
We have many relatives in the Bay area–they moved out from the midwest in the 70’s–and they love it. We visit often, but for us, “our place” is in La Jolla, and we wouldn’t trade it for anything else in the world. With many generations of each of our families here, our lifestyle, and the great weather–this is truly our “home.”
Those who, for whatever reason, don’t like San Diego, should certainly feel free to leave.
