Answer:
They were different because Katniss is having trouble with the interview because she does not like the situation she is in. She feels as though she is being fake up on stage and that is not her personality. Whereas, peeta makes a joke about the showers in the capitol, and Caesar states that Peeta is "charming and has a wonderful sense of humor." He also revealed that he has had a crush on Katniss, his female counterpart, for a long time, which started the star crossed lovers from district twelve story. Peeta and Katniss don't have many similarities; however they're both from District 12. They have to go against each other in The Games. ... They both have a protective instinct; Katniss over Gale, Prim and Rue, and Peeta over primarily Katniss – both would die for those they loved.
Hope this helps :)
