The scene around you is hard to understand. There's so many people shouting and running and bleeding. Everything is loud. You were only trying to find your mother in the crowd when all hell broke loose.

You're knocked the ground by a fleeing bystander and for a few moments, you can only assume that everything is over for you. But after a few seconds, you feel someone yank you up by the back of your shirt.

"I'm going to pick you up. Don't fight it."
