Carrie Pearl Weaver (born April 2, 1933) is the maternal grandmother of the older main protagonist of the story. This character is based on the real-life grandmother of the creator of The '00s. She is only seen in the pilot chapter throughout the entire first book of the series when Jamal and her mother both moved out.

Just like in real life, the birthdays of Jamal's mother and maternal grandmother are only one day apart following Fools' Day. Both birthdays also come very close to Easter every year. There may have been times when Easter Sunday landed on either birthdays.
