I was having a contagious flu during one period. I was honored to be isolated from the class.

My pocket was full of tissue papers, ready to prepare for war.

For the second period, the whole class was running on the track. I was struggling to climb the stairs 

Suddenly, a person pushed me down. I rolled down that 5-6 flights of stairs. The world was spinning.

Screams, gasps and scoldings were heard.

My vision was blur, I couldn't see well. I couldn't help but to cry.

10-15minutes felt like eternal.

When my vision was cleared, I saw you pressing a guy against the wall, ready to punch your fist right in front of me.

You told me angrily into my ear, he was the one that pushed you down.

I hurriedly stood up to break you guys apart. Looking at your raging face, I couldn't help but to feel touched.

"It wasn't on purpose, don't hit him." I said.

You ditched my hand, looked at me, and left without saying a word.

I stood still on the ground. What had I say wrong?
