As her classmates chimed in and started describing what they thought a pointer was, Sierra raised her hand. Pointer. That seemed pretty self-explanatory. "It sounds like a stone that has a point to it, maybe a point that leads you in a certain direction or toward another stone," she suggested. She shrugged to herself. She really didn't know what a pointer was, but based on what they'd been talking about added to what she thought the word pointer meant, it all sounded good to her.
