Alvin Ho needs help. He is afraid of EVERYTHING, well almost everything. The short list includes elevators, tunnels, bridges, airplanes, thunder, substitute teachers, kimchi, wasabi, the dark, heights, scary movies, scary dreams, shots, and school. His fear of school is the worst one by far because Alvin can't talk when he's afraid, making Alvin silent at school. Flea his desk partner says that he talks with his eyes at school and his mouth at home. Without a voice, it is hard to make friends. Alvin feels like he is really missing out. Maybe his PDK, Personal Disaster Kit, will help.
