From Damodar Anna's perspective, why did he become so angry at Mavshibai's joke?

Damodar Anna became angry because he felt Mavshibai's joke was a public and unjust accusation. As an elderly man, being accused of trying to kiss her and having 'no shame for your gray hair' was embarrassing and provoked his sense of dignity. According to Chapter 24, his immediate defense was to deny the charge and place the blame back on her. He rolled up his sleeves and retorted, 'Am I such an old man? Am I a fool or completely mad? You yourself put your face to my face and are ready to quarrel with me.' This response shows that from his perspective, she had initiated the physical proximity and was now unfairly making him the target of a quarrel.
