In his article "Alice on the Stage," Carroll wrote "And the White Rabbit, what of him? Was he framed on the "Alice" lines, or meant as a contrast? As a contrast, distinctly. For her 'youth,' 'audacity,' 'vigour,' and 'swift directness of purpose,' read 'elderly,' 'timid,' 'feeble,' and 'nervously shilly-shallying,' and you will get something of what I meant him to be. I think the White Rabbit should wear spectacles. I'm sure his voice should quaver, and his knees quiver, and his whole air suggest a total inability to say 'Boo' to a goose!"
Overall, the White Rabbit seems to shift back and forth between pompous behaviour towards his underlings, such as his servants, and grovelling, obsequious behaviour towards his superiors, such as the Duchess and King and Queen of Hearts, in direct contrast to Alice, who is reasonably polite to everyone she meets.
