I'm curious about why you're so judgmental of your friend's
maturity. Could it be your insecurity when she challenges
your philosophical or religious beliefs? No two people are
exactly the same so why do you deny friendship to her when
the world is based on different views, outlooks or rules. It
sounds like you're being a bit selfish and conceited about
deciding whether your friend is worthy of you. You should
remember your Dad's words because there may come a time when you are lonely and vulnerable and lose a valued
friendship. Granted, you recognize there are problems in your friendship but maybe focus a little more on the good in your friend instead of abandoning her because she doesn't
understand your depth of maturity. You say you're 15 - wait till you have a relationship or get married and then see if your ideals about being intimate will go over with the other person. The world is full of flawed, vulnerable people and as a bit of a perfectionist myself I can tell you I have lived to
regret rejecting friendship because what goes around comes around. How would you feel if you met a 16 year old you really liked and she decided you were too immature for her? I hope you remain friends with this girl just as you care for a younger sister or brother for example. But if you
expect people to follow your rules of friendship you are being intolerant. Talk to her in a nice way and help her mature if that is so important to you. There is no perfect
friendship. -Greg
