With Stella and Marni's birthdays just a month or two away, the girls have started to use their respective birthdays as leverage to get what they want from each other.For example...
If Stella wants a toy that Marni is currently playing with, then she will tell Marni to give her the toy or else she will not be invited to her birthday.
Or...
If one of the girls pisses off the other, then you may hear "You are not coming to my birthday party!".
The second example (punitive) is more often used by both girls while the first example (extortion) is usually only used by Stella.
