this little tidbit would not leave me alone, so here it is before it burns a hole in my brain
Arnold had always been a careful child, he didn't know if it was because when he was small he had fallen down an open well, or more likely that no matter where he went, things seemed to go wrong. When he first met Mrs. Frizzle on the first day of school, something in her glimmering eyes told him to run the other way as fast as he could. This feeling, which had saved him a broken arm just last week had always served him in the past, and was in the midst of trying to escape when he realized that his mother was blocking the door.
'traitor' he mouthed at her as she pushed him towards a seat. It didn't take him long to notice that the teacher wasn't the only thing in the class that screamed 'danger!' There was a sharp looking skeleton that grinned at him as he glanced at it, a model of the solar system that gleamed unnaturally, and on the teachers desk sat a large green lizard that Arnold swore was licking its lips as it observed the class. The teacher was what really got him though. How could no one else notice the unnatural gleam in her eye, or the way her dress seemed to shimmer as it randomly changed from one scene to the next, or that her earrings glowed?
He learned after the first fieldtrip that the other children were too enticed by the magic to notice anything, including the danger the Teacher had willingly and gleefully lead them into. He tried to talk some sense into the scientific Dorothy Anne only to be pushed away, she was only interested in the how's and why's of the bus or what she could tell them about their latest field trip to notice anything. When he tried Pheobe the only other girl in class that seemed to not enjoy the trips, being too busy talking about her old school, he found that she was too wrapped up in stealing secret looks at carlos to be much interested in anything he had to say. He had even tried talking to Janet about his teacher and the strange fieldtrips, but without evidence, it was like talking to a brick wall.
"You may have pulled the wool over their eyes, but one day i'll prove to the world that you aren't what you say you are." He had said to her when they had one of their few alone moments
"You can try Arnold" she said as she smiled "You can try..."
End
I always found it a little odd that the parents don't say anything about all the field trips the kids take, or that any of the kids don't say something about the danger they face every field trip. (whether you admit it or not, Mrs. Frizzle purpously puts her class in danger)
