This is also the first time that the children feel that amount of grief. “The class took it pretty hard”. Until this point they hadn’t really shown genuine emotion concerning the deaths before. For the first one, all we know is that there were “All these kids looking at these little brown sticks”, and we know that “they weren’t too disturbed” when they found out about the snakes. Although we can assume that they would’ve been quite sad about the puppy too because they cared so much about it and the teacher is saying “I got it out of there before the kids got to school”.
