text_A: Overall, Sanchez described Castro as a compulsive lover or "womanizer"; he has been officially married twice but has carried on numerous affairs, including many one-night stands. Popular with women and often recognized as a sex symbol in Cuba, Castro never had difficulty in finding love and seduction, and Sanchez denies that Castro ever engaged in any unusual or un-consensual behavior. Castro was also described as a poor father; he had little interest in the activities of his children and was more interested in his work even when he was at home, or otherwise keeping up the appearance of a devoted family man. Raul, who had much more stronger paternal feelings towards his family, was often the one who played the role of surrogate father to Castro's children, in particular Fidelito and Alina.
text_B: Would it often be the case that Castro would be surprised at how tall his children had grown, or how much they had otherwise developed, when he saw them after spending a spell concentrating on his work?
NO.
