And when people are afraid of me, I suddenly grow into a giant and everybody runs away from me. YOU are not afraid of me, so I stayed small. Do you  49  it? It's crazy! Please help me!"
"I can take you for a walk through our village," the girl responded. "I want everyone to hear of your problem. When they know the truth, they will no  50  be afraid of you. While we are going from house to house you can look at me  51  , and then you will stay the same size as you are now.

"Will you hold my hand  54  ? If I get scared I'll shut my eyes. Oh, and will you please call me  55  ."
