20 years after that day at Columbine High School, I’m still asking: ‘Am I safe?’

The drop-off of my child at nursery school, the hug, the fear. The thought: This could be the last time. Immediately, I put that thought away. He is safe. The sounds of rumbling as I sit in my college lecture. The thought: People are running, how do I get out of here, and fast? I realize it's the pencil sharpener. I am safe.
