●A Terrible Experience - revise

  As usual, I went home by bus and then I had a chat with my classmates customarily.  All at once, one of my classmates bursted out screaming with fear frighten me.  Out of curiosity, I looked out of the window and saw the man she pointed to; moreover, I opened wide my eyes as far as possible so that I could observe carefully. To begin with, I just saw a man wearing a black face mask on his motorcycle. At the same time, I suddenly caught such a disgusting sight of his jeans─ he showed up his “private part”; what is worse, he followed the tracks of our bus.

Fortunately, there was a clever mate. She made a phone call to one teacher, and then we followed what the teacher had suggested us. Eventually, we shook off the abnormal and winded up this unforgettable panic.  Although we underwent the hardship, my heart still flutter with fear.
