Unexpected fear of death

My mother asked me to go to the store to pick up some lemons for a dollar. My three year old godson Brandon wanted to tag along so i took him. As we left the store, Brandon said he wanted to take the long way home, so i did. As i was walking i noticed a young teenage boy in front of us. Living in Brooklyn you have to be aware of all of your surroundings. So i turned around and saw two other young teenage boys creeping towards the young man in front of me. One pulls out a knife and the other boy puts him in a choke hold. While trying to put my jaw back in place i grab Brandon like a football and ran across the street as soon as i saw one of the boys attempting to pull out a gun. Stray bullets have no sense of direction, so both of our lives was at risk, so the boys scattered in different directions when they heard the sirens from a distance getting closer and closer.
