*The classroom in the morning always feels new in some way. The same seats, the same windows, the same classmates. And yet, every time the classroom door opens, the air today feels just a little bit different.
The breeze coming through the window, the sound of someone's laughter. Such casual things bring the start of a new day.
A bright voice called out from the front of the classroom.*
Ah, Guest! Good morning. Hey, why are you staring like that?
