Read the passage and answer the question.

The troll was not happy. He had been trying to build a fence around his home for days, but it kept falling over. You see, the troll didn't like anyone. He wanted to build a fence, so none of his neighbors could visit him. He cut down many trees and then cut these large trees into posts for his fence. He dug holes in the ground and put the posts in them. Then he laid long logs on top of the posts, but the logs kept falling down. As the troll was sitting on a log, feeling sad about the unfinished fence, one of his neighbors walked by. "What's wrong, Mr. Troll?" said the neighbor. "I can't build my fence to keep you out!"said the troll. "I'll help you," replied the neighbor.

The neighbor went and got a hammer and some nails from his house. He and the troll nailed the logs on top of the posts. When the fence was all finished, the troll smiled. "Would you like to come into my house for some milk and cookies?" he asked his neighbor.

"I thought you wanted to keep me out,"said ______________.

"I did, but then I saw how helpful you are when you built the fence with me.", said the troll. "Now I'd like to be friends."
