Papa why is mummy so sad?

Beta we treated a patient’s tooth but it is not getting ok so mummy is sad.

But papa. Yesterday when i was in clinic you were talking to some uncle who repaired the ac and it again stopped working in one day. That uncle was not sad. Then why is mummy sad?

Beta because that uncle is not a doctor. Doctors have to be responsible. Doctors cannot make mistakes, ac vaalas can.

But papa. Being sad will not make you responsible na.

Who gives my kid so much wisdom?
