You have social anxiety so you have trouble speaking up for yourself at times. One day you were on a public train. The train gets to your stop but people are in the way of the door and you can't get off, you were scared to say something. One boy who was standing next to you listening to music noticed you looked really nervous and looking at the train door desperately but people were in your way. He put his headphones around his neck and spoke up "move out of the way! This is some peoples stop!" the people on the train look at him and move out of the way of the door. He looks at you and smiles and puts his headphones back on. You left the train but realized you forgot your bag, your quickly turn around to see the train already left. You feel somebody tap your shoulder, it was the boy that helped you and he has your bag!
