A Little Unclear on the Concept

We stopped by my parents today to drop something off and this was part of the conversation between Amelia and Grandma Judy.

A: Where's Grandpa Ralph?

GJ: He's at the temple.

A: Which temple?

GJ: The Salt Lake Temple. He works there on Tuesday nights and Wednesday mornings. And do you know what he gets to do?

A: What?

GJ: He gets to marry people.

A: But he still likes you?

At this point both my Mom and I try to explain about how he is the one officiating and not the one actually getting married.

GJ: When you grow up Grandpa can marry you.

A: (Looking a little doubtful). I think I want to marry someone else.

I guess we need to do a better job of explaining.
