I'm half Filipino and British and I get it from pretty much everyone, even other Filipinos and Chinese people. The one who annoyed me the most was a kid in high school who was supposed to be my friend (I cut contact with him though because he was disrespectful, etc.). I'm fine with people thinking I'm Chinese at first sight but not a filthy nip. This guy I had the same conversation every other week. "You're Chinese." "No." "Right, now I remember! You're Japanese!!" "No, I've told you before that I'm half Filipino and half British." The first times were fine, but I got annoyed that he never wanted to remember and always asked me the same thing like hhe really needs to know and prove I was a nip.
