Go to the cafeteria.

You walk through the main hall, and nearly jump at the laughing screech of the group of young woman beside you. Those high pitch squeals are enough to wake the dead. You regain your thoughts and walk through the narrow hallway and into the "student zone", then into the staircase leading to the basement, and the cafeteria.

You quickly realize there's nothing to do here. The lunch lady isn't there and there's hardly anybody around. The large clock in the middle of the cafeteria points that's about twenty minutes left before class starts again.

A sigh escapes you and you stand around a bit. This was quite possibly another useless trip of yours.
