I've got a similar situation but with my niece. I too have had the mind your own business remarks plus worse. I have been involved in her life since she was five when the family returned from living overseas. My other two nephews also live overseas so she is the only one I could be Auntie to. I thought it would be nice to try and be a good Auntie and take my niece out and about. I have also been called upon for plenty of babysitting (even overnight) and I've always helped out willingly. However, my niece has always been the rudest child I have ever come across and insincere with it. I've had doors slammed in my face, I've been ignored and also humiliated at one of her birthday parties. Her mother asked me to help with transporting 10 girls to bowling. When I arrived at the house to pick up my quota of girls, my niece turned to me and sneeringly asked what I was doing there. Naturally this was out of earshot of her mother. When I've babysat overnight, I've heard her make sneaky secret phone calls to her mother (my sister in law) telling her how awful I am. I suppose I should have told my brother and his wife what was going on but I didn't particularly want to snitch on her so I decided to ignore her when she was being unpleasant. On one occasion I was supposed to be taking her to a party and her mother asked me to do her hair. When it came to it, she wouldn't let me do her hair so I left her to it. She was being generally awkward. A bit later she came into the room and asked me how she looked (she is terribly vain) and I ignored her, repeatedly. Well, she did not like it one little bit. There have been loads of instances over the years, she is now nearly 16 and obviously my services are no longer required. I feel nothing towards this girl now. I find her unpleasant, disingenuous and sneaky.
