A tough teacher

I really like her, but man do I hate her! She will pick apart my slightest weight shift and make me feel like I just started dancing tango yesterday. After her class I feel like quitting altogether... But she's the only one who has been on my case about my "butt sticking out"... and I love her for that. Maybe some day I won't be struck by terror whenever she approaches me. I wonder what it would be like to date her!
