Susan Heffley

Susan Heffley, more commonly referred to as, "Mom", is the matriarch of the Heffley family. She's married to Frank Heffley, and is the mother of Rodrick, Greg, and Manny Heffley.

Appearance
Susan has a more distinct look from the rest of her family in the online and book version. She wears large glasses that cover up her eyes. She has appeared in the series without glasses while sleeping two times. She wears normal pants, either sweatpants or slim jeans, and a sweater.

In the movie, Susan has curly brown hair and a flawless complexion. She also appears with her trademark glasses. Unlike in the book and online version, she wears makeup.

Personality
She is a rather loving and caring mother, but she constantly embarrasses Greg and Rodrick, and appears to never care. Susan apparently knows very little about older children and often humiliates and ignores Greg and Rodrick to their dismay. She constantly tries to pull the family together, by getting Frank and Greg accustomed to Rodrick's band, tries to get Greg and Rodrick close to Frank, and tries to get Greg to enjoy reading, but none of her plans ever seem to work, and often end up in rather disastrous consequences for Greg and Rodrick. Especially when trying to hook the brothers together!
