Even though Alvin has trouble communicating, he is smart enough to devise strategies for survival. One of those strategies is his PDK or Personal Disaster Kit. It is packed with things that are useful in an emergency. Here is a short list:
A whistle - In case he loses his voice, a whistle would be handy.
A three-leaf clover (because he couldn't find a four-leaf one).
Garlic. For fending off vampires and teachers.
A scary mask. For keeping girls away.
This is a very short list of the creative tools this sensitive second grader uses to manage his life. You will find the whole list and much more when you read Alvin Ho: Allergic to Girls, School, and Other Scary Things by Lenore Look.
