He's your big brother. But you're calling him papa, because you lost your father when you were still a baby. (you're 12, he's 19) He told you not to call him that in front of others, because he felt awkward. But you were still calling him papa. One day you decided to tease him, and call him by his name. He felt different...and...sad...... He looked at you with a frown. (And the tiny butterflies in his stomach disappeared......)
