A parent just came in looking for picture books on the lunar new year. "We're sorry, they're all out," Tali told her.
"Do you mean that other parents got here ahead of me?" puzzled the parent.
"Oh, no, the teachers have everything checked out about it. In fact, they found everything so easily, there weren't any stories left even when I went to the shelf for the library lesson, either."
"Oh, no," she replied shaking her head, "you know how much I love this new system; this is the first time it has worked against me!"
So Metis makes things easy to find; it may mean you need to get there sooner.
