the worst grandma

 There was a grandma who had a poinsettia at Christmas time. Her two and a half year old granddaughter pulled all the red leaves off the plant while nobody was paying attention. The grandma would mention the incident every time the granddaughter visited her. The grandma was stern and there was no humor in the telling of the story. She clearly was still annoyed with the granddaughter - even when the granddaughter was an adult.

 Once upon a time there was a grandma who would give her two favorite granddaughters nice presents for Christmas. To the other granddaughter she would give the freebies that came when she bought her expensive department store cosmetics.
