Tweedle Dum | Alice In Wonderland Goblet

Literature has always been useful for expressing humanistic and social values - it is a reflection of society at the time.  It can explain both its good ethics and its troubles - either showing the positive values in society for people to imitate, or reflecting the worst of culture with the aim of making it better. 

“Tweedledum and Tweedledee
Agreed to have a battle;
For Tweedledum said Tweedledee
Had spoiled his nice new rattle.

Just then flew down a monstrous crow
As black as a tar-barrel;
Which frightened both the heroes so,
They quite forgot their quarrel.”

Upon meeting the two little fat men, Alice quotes the nursery rhyme, which the two brothers then go on to enact. They agree to have a battle, but never have one. When they see the Crow they take to their heels. The Tweedle brothers never contradict each other, even when one of them, according to the rhyme, "agrees to have a battle". Rather, they complement each other's words.
