would you boast about their good grades?
Granted my niece is a clever girl (18 this year). But the last two years, my sister has spent hours every day helping her with homework. Learning her maths and physics and biology, and spent hours explaining and doing her exercises and assignments with her.
It is nothing to do with me. I should not judge.
But yesterday my sis rang to share the sad news, she only got a 5 in Physics. In Norway, grades go from 1 to 6, with 6 being the top mark.
I said "But if your dd requires so much help, maybe she is not really a 6 in Physics" Reply? "Oh, but the physics teacher does not know I am helping her".
Surely, if she was a natural 6, she would not require any help?! The same story with Biology.
I know I am BU, because it is nothing to do with me, but I am sick of endless boasts about how clever she is, and how well she is doing.
I once tried to say to my sister that my sons teacher prefer the parents NOT to help with homework, as then the teacher wont know what the problems are, and cant go through it in class.
She said, "oh, but without me, it wont get done". So surely not working to a 6 grade then?
In one conversation I asked her what she thinks it will be like in Uni, as she wont have her mum there to push her, and she said she hoped she would have matured enough by then. I do find it really sad though. 
If I call her and we are chatting, I sometimes hear literal wails in the background, and my sis says "oh she has a problem, I must go calm her down". It does not bode well does it?
I personally think that my sister is so lonely, and have no life, and thoroughly live through her daughter, and enjoy the drama and being so needed. I really think she thrives on it, and has made herself indispensable rather than help her daughter to work and learn independently.
I just needed a rant. I guess I will have evening after evening now, of how unfair it is that she did not get 6 in Physics and Biology.
