I didnt stutter while reading a paragraph..

I didnt stutter while reading a paragraph.. I live in south america but my first language is english, so while I was in an english zoom class, a teacher asked me to read a typical paragraph (since im the most fluent) , I was pretty tired and the teacher almost always asks me to read something in her class, I wasnt even thinking about my stutter or anything and I just read the whole thing without even thinking twice it was over. I wouldve atleast stuttered once or twice (my stutter is mild) but I guess I was not thinking and was in auto pilot...
