DanceMInd: Dear Janie: Get clear ...

If you have to ask this dancer tomorrow. Be clear with what you intentions are. The more you ramble on, or the more defensive you are about this request, you sound like you are hiding something. In the ballet world, not good.

SO get clear and then take a few breaths and go ask. 

You cannot control her response, but take charge of how you ask. 

"Mary, I am wondering if you could help me with these parts. I am having trouble (Or I need to review) .... Can you work with me today at 1:00 or tomorrow before rehearsal?"

Let us know -- 

Am planning the dates for this outcome/goal setting.  Spread the word so others can benefit.
