Gammie Heffley

Gammie Heffley is Greg, Rodrick and Manny's 95 years old great-grandmother and is the oldest living member of the Heffley family. She has only appeared in The Ugly Truth, but had a major role in the story. She has alot of wisdom, and often gives "The Talk" to her older grandchildren on the edge of becoming teenagers. Gammie likes visitors as she often makes meals for them. Her furniture is also very valuable, and people often leave sheets with their names so they can get it when Gammie dies. Her last appearance in the book is when she gives "The Talk" about how he shouldn't be too excited about growing up, but Greg leaves after she pulls up her leg to show Greg medical conditions older people can get.

Trivia

 * In a flashback in Cabin Fever, when Greg snook into his mother's email account to tell everyone to coordinate of the Christmas presents Greg will get, Gammie's name can be seen.
