The poem tells the story of a person who was bullied by a friend for about a year through hurtful messages and physical pushing. They became depressed and had thoughts of suicide. One day while riding their bike, someone or something stopped them from jumping off a mountain in an attempt to take their own life. The next day at school, they confronted their bully by shouting "NO!" and telling them they would stand up to the bullying. They realized standing up for themselves was the best thing to do and the bully needed to know they would no longer tolerate the harmful treatment. The overall message is that the next time someone feels scared and alone due to bullying, they should remember to stand up for themselves.
