No, I didn't learn English until I was six, which was eight years ago, and wasn't any good at it until I was seven.
English is annoying for me because of all the slang. In kindergarten, when I could pretty much understand what people said and could actually say, "No" and "yes", some kid asked me if I "Farted". At this point, I was like, "What is that?" So I took a wild pick and said "No". Good thing I picked No because I didn't, and when I asked my mom what a "Fart" was, she doubled over laughing. < <;
Mandarin Chinese is my first language, though I can't write anything other then "One, two, and three" and I can only speak it well enough to carry on a fluent conversation with many bumps in between.
