Messenger: Chapter 7 and 8

In chapter seven, Matty attended the Trade Mart. Seer said that it was very different than when he went; when Seer went, everyone was light spirited and were happy. During Matty's visit, everyone was very tense and they came empty handed, even those who were trading. The Trademaster asked the people two questions. The first question was, "Trade for what?", which the people answered loudly. people answered the second question in a whisper, which the Trademaster copied in a book. The second question was, "Trade away what?".
When Matty was finished telling Seer about his experience, Seer asked if Matty had noticed anything different about the people who had traded. When Matty thought about it, he realized that the lady who had traded for a gaming machine had changed. The lady was always very nurturing and kind to her crippled husband who was very slow. However, that night after she traded, she snapped at him for being slow.
In chapter eight, when Matty was going to pick up his puppy from Jean, she seemed troubled. When Matty asked what the matter was, Jean said that her father, Mentor (Matty's teacher), traded his "deepest self" for a woman. She said that he was getting taller, straighter, growing hair in his bald spot and his birthmark had disappeared completely. He became less patient, too. Mentor kicked the rascal of a puppy very hard, who he would normally enjoy taming. Mentor used to always welcome new ones, but now he wants to close the border and not let anyone in.
When Matty went to Leader, he told him abou his experience at the Trademart and about Jean and her father. During that visit, Leader gave the puppy his name: Frolic.
