Who is this on the water buffalo ?   That's my grand-father . He was a farmer . When he was young , he had to take the water buffalo to graze in the field .   Oh yes , that was the best job in most farm families . That's where many of them learned to play the flute .   My grandfather did that too . He used the time to study instead .   That's interesting . Go on !   My grand grandfather was a merchant who ran a small business . He couldn't afford to send my grand father to school .   So he became a self-taught man ?   Right . Later he was a soldier and a fireman in the village . When he was middle aged , he became a great man , quite famous .   In what field ?   As a leader of police officers in charge of the whole country .   Is he still in that that type of work .   No . He retired from that . He is a senator now .   Would you want to be a senator ?
