I finished the Ashtanga yoga primary series for the first time today, during led class with Sharath Jois.

After class I went up to him and thanked him, and said (jokingly):

Me: So Sunday at 7.30? (7.30 is when the there's led intermediate class)

Sharath: You? Not in this life!

We'll see, Sharath. We'll see...

Ok, I guess I'll stick with primary for now :)
