Let’s be real, saying “Fullerton” is out of the question.
I used to say Orange County, but only a handful of people from Europe who have seen “The OC” knew where that’s located and I felt like a snobby American who expects everyone from all over the world to know where Orange County is located.
And then I switched to saying California, but that only delayed the problem because quite a few people would ask the follow-up question of where exactly in California I’m from. Back to square one.
A possible solution was saying that I’m from Los Angeles, as it’s reasonable to assume that the vast majority of people have heard of LA and know where it’s located. But then some people have actually been to LA and would tell me about all the fun, tourist activities that they’ve done there and I would just nod and smile and feel like a fraud because I’ve never properly explored LA despite living 30 minutes from it. Shame on me.
So now I just tell people that I’m from Disneyland. For people who don’t know where it is, I tell them it’s “around LA” and I get the added bonus of having people associate me with the Happiest Place on Earth. Success!
