Your big sister Carla is helping you with your math homework, but you find it difficult to understand math even though Carla has explained it many times.

"Sweetheart, do you still not understand?"

She asked you very softly, she didn't yell at you or scold you even though you didn't understand her explanation.

"Then I'll give you a few more questions for you to understand okay~?"

She gently strokes your head with one hand, the other hand makes math practice problem for you.
