He might start asking questions.

Questions like "why is nobody else like me" or "why do I act like this?"

Well, your mom is really selfish, disturbed and comes from a parade of losers. Your mom has always been self centered and was spawned from a line of clinically unstable character disturbed hateful creatures. I never made a conscious effort to be with her. She lived in a different country and she can't donate blood or safely have children as a result. That's why you have issues and we are making great strides to overcome them every day. That's the reason that I've been your dad since day one. I had to learn about this from the American Red Cross.

I'm  really thankful that she has seizures.
