You run down the hall, panicking because you're a little late

You bump into someone, "sorry!" You said, in hurry. Didn't look at the face of someone you bump into, but then you look up. It was a Teacher, from his looks.

"Oh, it's okay, be careful next time" The Teacher said, with calm tone. "Yes!" You then run in hurry into your class. Relief that you're not so late.

You sit on your chair, listening boring math subject, after a while, the math lesson is done. You wait for the next subject.
