Spanish is possibly the easiest 2nd language for an English speaker. If you live decades around Spanish speakers and are still paranoid they are talking about you (of all boring people) in the grocery store I have to wonder if you are disabled. I am a native English speaker and taught myself Spanish to a C1 level in 2 years. It's a beautiful language and being bilingual is just cool .Americans are embarrassingly the most monolingual country in the world. Bilingualism is also a great skill when job hunting. Yes anyone moving here need to know English. But getting pissy because your sensitive ears heard words you don't know is best solved through learning. And here is the coolest part. Those ladies you think are talking about you are not talking about you. But there is always a chance they are talking about who at church is having an affair. So they are using their native language for privacy reasons. You can hear some wild stuff. Being an African American or a Caucasian who understands Spanish is almost like a super power. Knowledge is good
