I do not know nor will I speculate what king of father Mr. Rooney was to his children. It is a well known fact, however, that children generally learn their thinking and develop their attitudes from their parents. If dad is a wife beater or cheat most likely so too will be his sons. If mom is slovenly or a drunkard there is good chance her daughters will follow suit.
Care for your kids with love and kindness, be the best example that you can be, for one day your kids may be taking care of you.
