Yes or No?

At the library concert, the songwriter and performer Les Julian asked kids to raise their hands if:
You like to sing.
You like to sing but are so shy that sing only when you are alone in the shower.
You are so shy about the singing that you would not even raise your hand right now.

How can you answer "yes" to the last question?
And how would you answer "no"...
Can you give your own example of a similar logical confusion?
