A school class had a special visitor. He asked the audience, "If you could choose between either having the super power to fly or to be invisible what would you choose?"

About six people rose their hands to answer his question.
He called on this one girl sitting in the back, she was very shy. She almost never talk to anyone.
She stood up and her exact words were-
"I would choose to have the ability to fly because you don't need a super power to be invisible."
