This quote suggests that animosities or enmities are often long-lasting and can extend across generations. It implies that if someone was an adversary to one's parent (the "father" in the quote), it is unlikely that they could genuinely become a friend to the child. This can reflect inherited conflicts, mistrust, or the enduring nature of certain hostilities, emphasizing how past grievances can influence present and future relationships, even when the individuals involved are part of a different generation.
