Answer

He felt that he was not listened to. He was the oldest and felt that the young people should listen to him, however they did not listen to him and the young people wanted him to do what they said/wanted. Thus this situation was opposite to what he wanted (reverse situation)

'It was more like the reverse' (more like the opposite to what he expected/wanted)
