Especially since Alice spends most of this exchange trying not to laugh, it reminds the reader that language and creativity can be fun and humorous—even if, in practice, suggestions like the White Knight's are wildly out of touch with reality. However, being able to consider these possibilities, the novel suggests, makes life richer. People who try to suppress this kind of thinking (like Alice, in this case) are shutting themselves off from a world in which anything can happen—a world that Carroll suggests is most present for children.
