My Friend: "How does he treat you?"

Me: *Dressed in princess costume lounging on the couch eating chocolate covered strawberries and cherries* "Fine. He could do better."

Based on your response, it seems like you are jokingly suggesting that your friend could treat you better. However, if we want to give a more meaningful answer to the question, "How does he treat you?", we need more information about who "he" refers to in this context. Is "he" a specific person in your life?
