Andrew Lice Clay shows up one day in class. Gilbert is immediately taken by the guest, and invites him to stay. But Adam suspects Andrew may be looking for a new home, on the scalp of a child. Upon getting to know the louse, we explore what these insects look for in potential homes, and what can be done to limit an outbreak. In addition to learning about the countless applications for treating lice, we are reminded that everyone is susceptible to these insects, and should not feel ashamed when they appear.
