To my Spanish people who don't speak Spanish...

How do you respond to the "How do you live in Miami and don't speak Spanish?" Or "How are you a Hispanic in Miami and don't speak Spanish?"

I've always struggled with my Spanish, but I can get by on basic conversation. I understand it much more than I speak it, which I feel is a big majority of people my age (millennials). I'm cuban/puerto rican born in Miami, but my first language was English and my second was 'Spanglish' pretty much. I can order food in Spanish and do talk about basic stuff, but if you wanted me to describe a medical issue I'm having or anything niche, than I pull out my phone.

I despise when people ask me, in Spanish, how can I live in Miami and not speak Spanish... I feel like I'm going crazy because I don't know what to say in response! One of my parents, who is a cuban immigrant and now a US citizen (came here legally a billion years ago), told me to say "How do you live in the United States and expect everyone to speak Spanish?" But that just sounds a teeny bit ruder than I would like.

What do you guys say instead? I'm so curious to know.
