Eh, I’ll give her a pass on the Cupertino bit. If my sister hadn’t lived near there, I might not know where it is either. And even now I didn’t know that’s where Apple started! (San Francisco area to me.). Silicon Valley, okay — but there are other cities included in that area.
When you’re from an area, you tend to assume everyone knows the towns, etc.. Years ago, I got used to hearing “oh, Chicago?” when I said I had moved to CA from MN and had grown up in Wisconsin!!! lol. (Now back in MN, FYI.)
