hmm i had this same problem a while back. I started teaching when i was 15, and alot of the students didnt like to show the respect becuase- a. I was a fellow classmate for many years b. the adults didnt like the fact that a young guy was directing them and fixing them. Well long story short, after 4 years now i have come to realize many things about martial arts respect. 1. I was big on the whole- " you better act right or ill give you pushups." never worked... till i gave them pushups. Also if there was a student being rude and disrespectful fine, have them sit and watch the others do something fun, or better yet praise the good students 2. set the example. dont just demand respect on the mat, earn it on/off the mat by the way you act and converse with others. 3. Set the line between friend and student/teacher. to close a friendship with kids and they wil try to take advantage of you. BTW how old are you? hope this helps- -Kevin
