Rubina's baby sister is a brat, and her mother is no help. In fact, her mother encourages the brattiness by giving in to bratty tantrums so it's no wonder really. I think I'm supposed to find the ending uplifting, as Rubina rises above and becomes the better person, but all I can think is that this poor child has no birthday invitations and no friends left because the brat and the mother who spoilt her have chased them all away. A lollipop is hardly compensation.
