who meets a champion boxer friend on the street and says, "Hey, Champ, how are you? Should Champ always be capitalized? And how about when a guy calls his fiance honey in dialogue? Should he always capitalize Honey? And when a kid calls his dad Pop to his dad's face, should it too always be capitalized? And lastly, in the case of a mother calling her son Pumpkin in dialogue, should Pumpkin always be capitalized? Thanks in advance. Thanks.
