Yes, I have had that experience. I overcame it by asking what they meant. It hurt me, but when I asked them what they meant they stopped. Now we are friends. We go everywhere together. We have parties, sleepovers, and movie nights. Once I have used poor diction on accident. The person I used it on never forgave me. I am very sorry about that right now. From that moment, I have been careful with my diction. Whenever I think of saying a poor diction, I stop and think, should I, or should I just keep quiet. I always choose to keep quiet, so that I don't hurt someone's feelings.
