i remember a long time ago i was at my bros freinds house and there neighbour came over, then when the mom came she said "ready to come home dear?" and he said "N-n-n-n-n-nm-n-n-n-n-n-n-n-n-n-noooooooooo" and i was like O_O robot! but i think its a symptom like ADD, how it is based in your brain
Some people that have been through abuse or other kinds of trauma may studder but most people studder simply because they're insecure, have a speech problem, are nervous, lying or just coz their mind thinks too fast for their mouth
i found that i stutter quite abit know, instead of waiting and not saying anything while i think, i stutter my letters or words until i think of what to say.
i dont have ADD and sometimes i studder on words with alot of "M"s in it..doesn't mean my brain wont let me..it's my mouth that wont let me..lol..
some people like me, think too fast. we think faster than we speak thats my problem anyways
some people jusy simply studder. others, maybe because ther nervous, lying, or something
nervous lying shy dont know what to say or a habit
