He was afraid that he may be made to disappear unceremoniously by those whom he opposed at his workplace.
They were living in a far away country - far far away from homeland. So he decided to make his family strong enough to face any unpleasant and unforeseen developments.
He succeeded in making his wife and only daughter very strong. But that is not the end of the story.
He had made them so strong that they eventually also became head strong.
They had their own minds which literally means the They will NOT listen to anyone or anything.
So his entire scheme backfired like the U turn twist in the O' Henry stories.
He is torn asunder by the three women in his life... his mother, his wife and his daughter.
They all appear so frail and weak in comparison to his impressive stature but he is
merely a puppet in their hands.
On second thoughts instead of making the women in his life stronger,
it might have been a better idea to have made HIMSELF stronger! :tsk:
