Crowds of angry , smelly people were bitching and bumping into each other , and into me , trying to get their copy of whatever textbook they needed for whatever stupid class they were taking . One lady asked to herself out loud " Where is 237 ? " when she was looking at the History section of books .
According to the above context, answer the following question.
Why may the people have been unhappy ?


It was crowded , hot , and difficult to get their books .
