MINE and YOURS...

Here's how it went:

Me: I love you bud!
Cayson: Love you too mom.
Guess what mom?
Me: What?
Cayson: I'm yours!
Me: I know, you are mine and guess what?...I'm yours too!
Cayson: So I am yours and you are mine!?
I'm dad's too mom.
Me: Yup, you are dad's and mine, we both love you huh!
Cayson: I know. (then he sat and thought for a minute)
Mom, I am dad's not yours anymore.
Me: What? You are mine, why did you say that?
Cayson: Dad shares his mustang with me, and he takes me for rides...
you don't do that. (then he thought again)
Mom...I'm yours and mine, and dad's mustang is yours and mine too.

That works for me! : )
