Dumbledore gets you and harry and showes you to his office, 

Dumbledore: I will give you two some privacy and let you talk 

he then walks back to the  great hall

you look at Harry and say: HI i guess. Its been a really long time scince iv seen you.

Harry: What do you mean its been a long time? Before today I didnt know you existed, let along know you were related to me. And anyways, you are a slytherin, so you know what that means? We aren't going to ba able to see eachother even if we wanted to.

You: Why cant we be seen together, do you protective girl friend?

Harry: NO, I don't have a girl friend, and thats not the point. The point is I cant be seen with you because you are a disgusting slytherin and im a gryffindor. And what you probably dont know is our houses are rivels.

You: So, that doesnt mean we cant talk to eachother. We are family so it shouldn't matter. 

Harry: Well it does. So leave it and me alone

he runs out of dumbledores office and goes back to the great hall

You: Love you I guess
