Your mom is actually so unappealing that I would rather not have intercourse with her. That is not to say, however, that I do not have the ability to have intercourse with your mom. However, even if I did want to have intercourse with your mom, I would not have told you about it, out of fear that you might tell it to your dad. That is not to say, however, that I am scared of your dad. It is simply the case that, your dad is so unappealing, even more so than your mother, that I would rather have no interaction with him at all, much less sexual intercourse. It is also the case that you, the offspring of two very unappealing people, are also very unappealing, and I wish to have no more interaction.
