Marriage

Autumn: I love you, Kyle, you are the bestest brother in the world. I want to marry you!
Kyle smiles.
Mama: Well, marriage is just for adults.
Kyle: We can get married when we become adult.
M: I mean brother and sister can't get married.
K: Why? (He seems to be interesting in marrying Autumn? Mama thinks)
M: Marriage is for two strangers, people that don't live in the same house, they met, they fell in love, and they get married.
A: Why, Kyle and I love each other.
M: But you are brother and sister. Mama and Papa are not brother and sister.
K & A: Oh....

Was that convincing? Do they still think that they can marry each other? What an interesting topic to talk about at the kitchen table in the dining room.
