For crying out loud! Leave her alone dammit! She lived an entire life figuring out how to learn. How do you even dare to think you know better?
1. You haven't met her.
2. You have probably never heard her play
3. You haven't met her teacher.
4. You haven't been her for an entire life
5. You haven't seen her progress - you don't know where she started and where she is
6. You haven't asked about her goals yet
7. You haven't asked her teacher about neither her abilities or progress
Dammit, don't always think you know eeeeeheeeeverything better than everyone!
For you it might work, but she clearly tried, and it didn't work.
It's not even funny how you always do this. Every topic you enter turns into this. Someone says "No, it doesn't work for me" and you say "NO, YOU ARE WRONG!! I WAS LIKE THAT! NOW I'M BETTER AND I KNOW BETTER THAN YOU!!!". just.. Gah, grow up!
