The naive person gets upset even when / Someone unrelated to me, who is sincere, does so. (Meaning: A naive person becomes upset/angry without reason, whereas a sincere and pure person would not.)

This beautiful couplet captures the deep pain of being misunderstood by the one person you love the most. Mir Taqi Mir describes the heartache when even an innocent, naive soul gets upset—and the source of this hurt is someone who is completely sincere and has no justifiable reason to be angry. It speaks to the fragility of trust and the unexpected sorrow that comes when love itself becomes a source of pain.
