My native tongue is English. I've learned both Chinese (my parents are Chinese) and Spanish. In Spanish, my stutter was roughly the same, but in Chinese, my stutter is 10x worse. I don't know why, and it's a bummer because when Chinese people try to talk to me, I look like I can't even speak my parents' language when really, I'm just stuttering. I've even had Chinese people laugh at me for it because they don't get what's going on. :(
