Flute I play guitar and try to play the bodran, sometimes I have a great session and sometimes I meet people like your person and it does upset me but at the end of the day I remind myself that i play for myself and While I am not a master of the guitar I have received enough compliments from musicians to let me know that I am ok. So what I am trying to say is "You can please some of the people some of the time, but you cannot please all of the people all of the time" Keep playing and f**k the begrudgers as we say in Ireland
