To follow up from yesterday's fiasco with Rosetta, I gathered up my courage to try again to talk the talk. I switched back to my old headset, the one that is broken and may possibly electrocute me, but it worked better than my new one from Radio Shack. So that's going back to the Shack!
My dignity is restored, my score improved to 87% in pronunciation, and I have the strength and confidence to continue.
I can't quit now anyway, I want to decipher the words they sing during my Zumba dance classes.
