Journalist: Hi, I’m a journalist from The New York Times, my name is Anthony. Before I start this interview, I would like you to know that if any questions make you uncomfortable you don’t have to answer them.
Student: okay.
Journalist: So, how did it all begin?
Student: It was Wednesday, and school started like any other day, until the last period during which I was in the library with a few other students. We heard a gunshot in the corridor. We panicked immediately until we regained our teacher and hid under the desk.
We waited for a long 30 minutes before we heard another gunshot, then another, that’s when we realized that the shooter was coming nearer to the library.
Journalist: My god! What next?
Student: We decided to run to the back of the library where it was very dark, we figured he wouldn’t find us there.
Journalist: Smart move! What happened after?
Student: We crawled to the back and felt relatively safe for a while. The window was open and the sun was setting! We had been in school for nearly four hours!
Journalist: Wow.
Student: Only after it got dark the police burst into the library and helped us all to safety.
Journalist: Hopefully there were no casualties, but a teacher was injured.
Student: Yes.
Journalist: Thank you very much.
Student: You’re welcome. Please make it a good article, it could’ve been worse; we need security in our schools.
This isn’t much but I hope it helps! <3 good luck on your assignment!!
