When I was growing up I had a speech problem, where I could not correctly pronounce the letters: 'r','s', or 'th'. I was always teased or bullied because of how I spoke, and I always felt humiliated like it was my fault, until I found it it was all caused by a simple overrbite and I went on to join speech team, and even receive a Judge's choice award which was really a honor, and felt to me like I overcame the odds. What I'm saying is, you shouldn't be cruel to someone because of how they speak. You never know, maybe they can't help it, and it certainly can happen to any one of us.
