Since we actually knew this family and the mother and our father were social acquaintances, living in the same city at the time, we don’t have any reason to think that the info is not true. There are too many details of time and location, that wouldn’t match up, if not true.
Exactly!
If this were some total stranger, you would be justified in being skeptical - but if turns out that you actually babysat this person, then the reality is: Your father had sexual relations with that neighbor woman.
Does this change your opinion of your father? I mean: The fact that he probably knew it was his child (that they were his children?), and yet abandoned them?
