Final answer:
Peeta Mellark surprises Katniss Everdeen at breakfast by talking with the other tributes in 'The Hunger Games', which is unexpected given the competitive nature of their situation.
Step-by-step explanation:
In the book The Hunger Games by Suzanne Collins, Peeta Mellark surprises Katniss Everdeen at breakfast by casually conversing with their competitors, the other tributes, which is unusual behaviour given the circumstances. This act of friendliness is out of the ordinary because the tributes are competitors in a battle to the death, and it is traditionally a time of mistrust and isolation among them.
His actions are in contrast to Katniss's approach of keeping to herself and remaining aloof from the other tributes. Peeta's amiable disposition and outright social engaging can be seen as a tactic to gain favor or simply a genuine aspect of his character.
