I had a realy long and nice discussion with an English native speaker. And we decided that bIvangDI’ yIqu’ “When you act, be fierce!” is the right thing. Thank you so much. Now I have to more things were you can help me.
1. Can you produce graphic of the pIqaD for me?
2. Is there an possibility that I can get a audio file, so that I know how to pronounce the sentence correctly?

That would be so great! Thank you so much!
