You are saying like "why you are crying, what if your father died, see that boy doesn't have father or mother." Just shut up. If you are saying pain or suffering, doesn't matter, why just comparing stutterer with blind or deaf people, compare blind or deaf people with animals, animals are living hell, compare to them humans suffering should be never mattered. So Do not compare. This is fucking behaviour of a living thing, everybody feels it. People will eventually forget if they don't meet again, but people like classmate, co-workers, family members, they don't, they are people who we are going to live with. They don't forget, and our stuttering is always there to make them remember how hard it is to communicate with us.
