Guys i wanna know something

Guys i wanna know something hm... so here it goes... i can read in front of my family , or even alone and you wouldn't even tell that i stutter, but when i am question to read in the classroom i don't read at all , i say "i don't want to read teacher" in all class... but the thing is ,do all stutters are like me when reading alone or with your family? seriously i don't stutter when i read alone, i only repeat some words , but that's normal every people repeats their words from time to time... it's part of the speech patern humans have, "hesitation, repetition and prolongation" Pls be honest with me, i really want to know what you guys fell when reading , be strong guys :)
