Here's the scoop: Apparently, when Pearl was 18, she became pregnant (presumably through the normal means and nothing incestuous) and her parents insisted that she give the baby away as to "not to bring the family into disrepute." (Yeah, I don't think her family would be all that thrilled with her current relationship if they were all worried about the disrepute and all. Sleeping with your grandson is a surefire ticket straight to disrepute. And probably to hell, also.)
So, Phil found an address for Pearl and he wrote to her. That's quaint. A letter. I wonder if he used a quill and an ink well to make her feel more comfortable? Regardless, Pearl said that she "... was stunned to get his letter...My heart jumped that I'd be re-united with a grandson. I wrote back immediately and included my phone number." To her rotary phone, I presume?
Pearl recalls that "From the first moment that I saw him, I knew we would never have a grandmother-grandson relationship. For the first time in years I felt sexually alive." Excuse me for a minute. I think I have something in my throat. I believe it's my lunch. EEWWWW!!
