“Well dressed 50 something business dude on a quiet Chicago L train reading a Wall Street Journal. Pretty woman with long curly hair dozing in the seat in front of him, her hair dangling behind the seat. The guy is rubbing and playing with her hair while reading his paper so I figure she’s his wife or girlfriend who just wanted some space to nap. He is now intently rubbing and fondling her hair and not reading anymore. Suddenly she snaps awake and pulls in her hair like a bug was in it or something. She gets off at the next stop, he continues reading. They didn’t know each other at all.”
