What if their teacher is impressed by the boldness of the stutterer persevering over their speech impediment and gives the student a higher score? And of course there are bullies and those who mock, but literally every single person on the face of the earth has been belittled or mocked for something in their lifetime, not just stutterers. We can choose to completely upend our lives in an attempt to please those who mock us or instead understand that bullies are dickheads and ignore them. That's a choice. We also need to understand the cognitive biases that severely impact many people to fixate on their own flaws to the point they ignore their own strengths and form a truly distorted view of the world, focusing on the negatives rather than a balanced view.
