Mrs. Riser

Mrs. Riser was Greg's teacher in his previous grade in The Last Straw. Greg mentions how he used to write hate letters to everyone in his class during Valentine's Day without signing it, however soon kids started to complain to Mrs. Riser, so she tried to find the culprit. To make sure he is not accused, Greg writes a card for himself too.
