What is April's nickname given to her by Ken and Toby?

Melanie is
worried about starting school because she fears that April will not make friends easily in sixth
grade. April is quirky, and although Melanie gets along well with her because they both have
creative imaginations, she doesn't think the other sixth graders will accept April's
idiosyncrasies. When Ken and Toby gave April the nickname "February," Melanie
"knew everything would be all right." Some nicknames are teasing and have a hurtful
tone to them. This nickname, however, isn't a belligerent way of calling someone by an
unfriendly name; rather, it is an innocuouseven friendlyway of rubbing April the wrong way
without meaning to be unkind. It's like the greetings Melanie's father gives April when she
comes over, saying that "the cruelest month is here." It acknowledges April's unique
name and personage without calling out any of her quirks in an unflattering way. The nickname
Ken and Toby give April shows that they accept herat least, as much as they accept any girl
their age.
