Jacob walked up to Ravenclaw tower. He hadn't eaten that much in 3 months, and now that he did, he had to walk up to the top Towers of the school. This was torture... complete inhumanity. But then again, it was pretty good exercise.

Jacob hit the knocker once, and the eagle spoke.

"What's made of stone, but is soft like a pillow?
Where you can float on top, or dive down in it?
Where you can sink underneath, but it doesn't crush you?"

Jacob's mouth opened and closed continuously, if someone was watching, he might have looked like a fish... "Uh... Sand?" he half said, half questioned. He thought these were usually logic, no actual answer. But obviously the knocker was being sill today.

When the door didn't budge, Jacob gave a small sigh. "Oh come on. Sand. It's made of stone, but it's soft when wet. You can lay on top... or sink underneath." it made sense, didn't it?

At that the door opened. Obviously the door wanted an explanation for his answer... "Darn door. Making things difficult!" he grumbled under his breath

Jacob made his way into the common room, and quickly made his way over to HIS couch. The one he had completely incinerated last term. He sat down, making sure his wand was in its holster and not his back pocket this time. When Jacob sat down, he took off his back pack, for the very first time in hours... He still had no reason to open it. He'd start charming the papers when he gets up to the common room.
