Tears of Joy.

Tori: I am so glad you are my brother.

Tristan: How come?

Tori: Because you're just fun and I like to play with you.

Me: Now tearing up while writing Christmas cards in a chair nearby.

Tori: What are you crying about over there?

Me: They are tears of joy that you guys love each other so much.

Tori: Well that's stupid, who cries when their happy?

So some sweet moments have sweet endings. Some dont. Guess which one this was?
