Describe Mr. Pignati from Zindel's The Pigman.
Mr. Pignati is an older gentleman who lives alone on Howard Avenue. His wife died awhile back, but he tells people that she is on vacation in California. He has a fun and interesting personality and he doesn't mind smiling a lot. He is also generous because when two teenagers, John and Lorraine, ask him for ten dollars for a fake charity, he willingly gives it to them. He invites the teenagers to get to know him better by joining him at his favorite place--the zoo. He introduces them to his best friend, Bobo, a baboon. Mr. Pignati is also generous because he buys the kids skates and then allows them to skate around in his house. He also winds up being like a father to Lorraine because he even buys her nylons that she needs, which she appreciates greatly. Mr. Pignati is so kind and generous that he fills a void in the tennagers' lives since both have issues at home with their own parents. In the end, he dies of a heart attack, but the kids are so grateful to him that they write a memorial book in his honor called The Pigman.
