Let's see... She doesn't know what the Rach3 is (I don't know if she'd know what the Hammerklaiver is, either). She doesn't know what ABRSM is. She is horribly ignorant. She never taught me sightreading, aural skills, interpretation, theory, etc. I still can't use a metronome correctly.

And she has a horrendous memory, forcing me to recount everything we've done at the last lesson to her. Either that or she just doesn't care.
Anyway, if I tell my mom I've outgrown her, she'll call me arrogant and my piano playing horrible.
She started piano at 9, quit during high school, picked it up again in college, and now works as a nurse and teaches piano part-time.
I started with her because there's like no one else we know. Her only positive trait is that she's cloyingly nice and encouraging and blah.
If I print it let her read this, she'll say I shouldn't waste my time on the Internet.
Anyway, we've reached a compromise. If I find a piano teacher by myself, she'll maybe let me switch. But only maybe, and depends on the rates.
I really expect to be different. To have more enthusiasm, to know more, etc. Like if a Bernhard like person becomes my new teacher.
And I'm absolutely forbidden to mention any of this to my teacher. My mom thinks it the absolute in rudeness.
