premise: A boy wearing a red cloth as a headband is having another person write on his cheeks with red magic marker. hypothesis: The sister pretends to put makeup on her brother.
neutral: Just because another person was writing, it does not imply that the boy's sister was writing, or that he even has a sister.  Writing on a boy's cheek does not imply that one pretends to do anything.  A magic marker is not necessarily a form of makeup.  Stating that a person wrote on her brother implies the person's gender, but simply referring to someone as a person does not imply any specific gender.  Just because the boy is male, it does not imply that he is another person's brother.
