I'll echo some of the other commentors here on accents. I grew up in the East Bay of SF and we have SAE, an Okie accent from our dustbowl migrant forefathers, and a valley-girl/surfer twang too. I speak SAE in mixed company, the Okie with older relatives, the 'surfer' accent with close friends and family of my generation, and SAE when nieces, nephews and other children are around during holidays. We would prefer the next generation either develop their own accents or forget ours. I would not dare use anything but SAE with co-workers, bosses, or customers around. As many transplants to the Bay are on HN, it may surprise you that the people that grew up around you, even in SF Bay, have accents they do not share with you around. What is more interesting is the lexigraphic and accented differences between places like SF, the south Bay, Napa, and even Sacramento. It's not easy, but within a few minutes, I think I can still place the speaker from one of those location, though with the younger generation I may just be BSing.
