I agree with Bo'sadvice. I encountered ths stuation recently with a girl-youth whom I have been corresponding with for over a year. She began to ask me for money. One or CD's and another time for hygiene items. It upset me deeply. I asked for advice from PDN and was given some great guidance on line with what Bo suggests. I did not want to be her piggybank, I wanted to be someone she could turn to for relevent advice on how to be positive and helpful in life and guide her in her Buddhist journey.
I told her no in a nice and caring way and I have not heard from her since. It is not our responsibility to make decisions for those we corespond with and befriend. It is our resonsibility to give positive and realistic advice. You cannot make someone understand or agree with everthing you say.
