Yeah Chris, the trolls TOTALLY killed your dad. Like, him dying totally didn't have anything to do with his cancer, failing heart, bug bites, and stress from living in that filthy shithole you called a house because your stupid, crazy bat of a mother wouldn't try to give him a clean, safe haven to die peacefully in. It was totally trolls who had nothing better to do with their time than torment a old man.
Oh wait, the few times trolls called the house and Bob talked to them, wasn't that the first intelligent conversation he had had in a long time? I remember one call he talked about being an engineer and stuff. I think in the last couple of years of his life, the trolls were the most mentally stimulating people in his life.
