Friends could act like parents..., Can they what do u think Options

[Jayembe]

My one friend is always on me and lecturing me of things that i should do and change and, that i shouldn't be mean. I believe that i'm not mean except to those who can or are mean to me. I'm starting to feel like she doesn't approve of me being me. She also calls me and lectures me for some little mistake i have done. She tells me these are mature conversations but, i dont want to be mature around my friends because then it's just boring although at times i am mature. Im starting to feel offended and very annoyed when she is around. Do you have any friends who do this and what should i tell her so it doesn't make her hate me. Oh yea and she is a hypocrite but, when i tell her she is she argues that she isn't and, backs it up with huge reasons.
