When I say that, I’m really asking questions like what city/state is on your ID/driver’s license, where you’re registered to vote, who you pay taxes to, which town you list as your permanent address on paperwork, and so on. Either option is valid, and I’m interested in what other people choose. Personally, my hometown is San Jose, and my college town is currently San Francisco. I live off campus, my driver’s license has a San Francisco address on it, I’m registered to vote in San Francisco (and I do vote in local level elections), I work in San Francisco, and I list my San Francisco apartment as my permanent address (I stayed in this apartment over the summer, but I was taking summer classes). I’ve pretty much cut any ties with my hometown outside of visiting family.
