Admitting My First Lie in the New City

I just moved to this city and I'm trying so hard to make friends. Yesterday at a coffee shop, someone asked if I'd been living here my whole life because I sounded like it. I said yeah, that's how badly I want them to think I fit in. It felt like such a tiny fib, but now every time they talk about 'local spots' or 'favorite city hangouts,' I cringe and feel so guilty. I should just admit the truth but who wants to be seen as new?
