The Boy and The Girl had spent an evening with their cousins, which to them is heaven on earth, and The Husband and I naturally asked them about their evening.

Me: What did you do?
TB: We played.
Me: Well, I assumed you played.  What did you play?
TB: Hide and Seek and War.
TH: The card game war?
TB: No, it’s this game with weapons.  You have a sword….

Both children proceeded to tell us all about war.  It seems like hide and seek but with imaginary weapons and some super powers.

TH: Did you make this up?

The Girl and The Boy responded simultaneously.

TG: Yes.
TB: No.

TH: You didn’t make this game up?

The Girl and The Boy begin talking over each other.

TG: Yes, we made it up.
TB: No, we didn’t make it up.

TH: If you didn’t make it up, where did you learn it?

The children finally take turns in their conversation.

TG: We made it up.
TB: No we didn’t.  Not today.
TH: But you did make it up?
TG: Yes.
TB: No.
TH: I don’t mean did you make it up today.  I’m just saying you guys made it up.
TG: Yes.
TB: No.
TG: Yes we did make it up.
TB: Not just us.  Our cousin did, too.
TH: I was talking about all of you.  As a group, you made up the game.
TB: Yes. *pause* But we didn’t make it up today.  We made it up last time.
TG: No, it was the time before that.  It was two times ago.
TB: Yeah, it was two times ago we made it up.  I don’t know.  I don’t even know what it’s called.  It’s just a game.
Me: But you just called it war.
TB: Yeah, we made it up, but it doesn’t even have a name or anything.  It’s just a game we play.
