I can understand about kids as they are dumb and do not know what is stuttering, so they mock. But elders? I my school time, every teacher of mine was always rude to me, infact hate me, because of stuttering, they thought this kid can not speak so he is dumbest in the class. As we know stuttering doesn't happen everytime we speak, when we speak to ourselves, when we sing and when we speak to our best friends, we don't stutter, because of that, teachers thought I am faking my stutter in front of them to get from oral exam or answers of the questions they asked in the class, because of that they hated me😫😫😫. My school life was livibg hell, everybody teachers and students hated me for no reason, without knowledge of stuttering.
