I did felt embaressed that I could do nothing to prevent those ppl making my teacher angry , he is old school pro high etique guy , that was probably 2nd situation I had as described above I had no fun fishing . Lucky me it was pretty easy to explain that it is easier to ignore them and move to different spot , cuz those guys won`t change their mind .... I don't like violence ... and I always try to prevent it ... and I did my part to prevent that ... but I still have even more respect to my teacher who tried to argue about etiquette and rules , although those guys were still yelling that "its not vedder" ... sad but true
