Chapter 6 in Paul Zindel's The Pigman is when John and Lorraine meet Mr. Pignati at the Baron Park Zoo. Lorraine doesn't like zoos anyway because she can't stand seeing the animals locked up and being treated poorly; so, she's nervous to start with. She's also a little bit superstitious because she takes a few circumstantial events as omens that the day will end badly. The first event that Lorraine takes as a bad omen is the fact that the lady selling peanuts was rude when she didn't need to be. 

"I mean, that's how antagonistic she was. A real devoted antagonist. You could tell she hated kids" (58).

The next bad omen is when Lorraine is attacked by a peacock. She explains by saying the following:

"This low-IQ peacock came tearing after me as soon as it heard me open my bag of peanuts. They let them run around loose at Baron Park Zoo, and this white one opened up all its feathers and started dancing in front of me and backing me up against the fence" (58).

The third and final bad omen is when they all walk into the nocturnal room to see the vampire bats. The bats weren't the omen, though. Lorraine gets freaked out by this ten year-old kid who is looking at people walking by the glass cage rather than looking at the bats behind it. The kid gives her a creepy grin and makes her feel like she is a bat in the cage and he is looking at her. 

Interestingly enough, the omens have something in common--they all have to do with Lorraine perceiving them as negative. She only feels attacked and victimized by the peanut lady, the peacock, and the little boy, but none of them were actually out to get her. For example, it's most likely that the lady selling peanuts simply couldn't hear Lorraine order "four bags" of peanuts. The lady's response of "Why didn't you say so?" was merely a result of bad hearing, not because she didn't like kids. Next, Lorraine over-reacts to the "attacking" peacock because, as Mr. Pignati tells her, it only wanted peanuts, not to hurt her. Finally, the little boy probably wasn't sitting at the bat cage attempting to creep people out. He probably just sensed Lorraine's nervousness and smirked because of it.
