Playing house with Grandma

Brianna and Grandma Linda each had a Barbie doll and were playing house. At one point, Brianna was playing the mother and Grandma Linda was pretending to be a whiny kid.

Grandma (in a whiny kid voice): I don't wanna play inside. I wanna go outside.
Laura (trying to help Brianna respond): Brianna, tell her not to be so whiny.
Grandma (whiny again): I wanna go outside.
Brianna: You can!
