This doesn't sound like a computerized voice. She sounds as though she really means it!

"I don't wanna know" is marked as wrong D:

I don't wanna know, know know, know...

Is the meaning of sapere to know how to do something,? If so surely the translation would say "I do not want to know it?

I don''t want to know was marked as incorrect and there is no way to report that, at least not today

The word "know" is missing.
