Hello! My name is David. I am from United States and I don't speak or understand Tagalog. Mainly bad words that my friends and I used when we were teenagers calling each other bakla and pangit. I'm just curious if anyone knows Ilocano too because that's what my parents spoke in my home while I was growing up and sometimes during conversations with others they switched between the 2 languages. Is it hard to speak and understand BOTH?????
