I remember September 11, 2001 very vividly.
I went to high school in Washington D.C. and was in my second period Spanish class when my personal cell phone began vibrating.
I ignored the it for fear of getting into trouble and then heard my name over the PA system requesting that I report to student services immediately. My mother was on the phone and told me about what was going on. The World Trade Center had been hit by two planes and another had crashed into the Pentagon.
