I wished I had thought to come here last night.

I had a senior dancer teaching a student in secret for a year and the "student" just signed up for my class last night. The senior dancer training her - just left for uni.

Do they not teach some kind of ethics anywhere anymore?

I might add I am the only teacher of my method in town and my senior dancer has no qualifications to teach. To her benefit, she did teach the "student" very well, but as you know, not entirely correctly.

Sad thing is, I can't even confront her! I wouldn't yell, but just explain the inappropriateness in case she pulls this in her new town where there is another teacher.
