Why?

My girlfriend G- is getting married today. Keegan knows her as Auntie G-, and he really really loves her because she drives a school bus in the summer, and I am pretty sure he thinks she OWNS it.
The other day we were driving home from daycare, and I like to tell him a couple of days ahead of time when he's having a babysitter. This gives him some time to figure out how many treats he can get out of her, and what outfit he's going to wear. He is in love with his babysitter. I don't blame him, she's gorgeous, and I am going to sob the day she graduates.
A fantastic babysitter is priceless.
"Momma and Daddy are going to Auntie G's wedding on Saturday so Sarah will be here."
"Who is she marrying."
"She's marrying S-."
"Is that a girl?"
"Yes, S- is a girl. You met her once when Maren was born. She's very pretty with blonde hair in a pony tail and-"
"Mom! There's our sidewalk! That's where we bike!"
And that was it.
We were done with the Auntie G- is getting married conversation.
And see I wanted to brake the car right on the busy road and scream and cry and yell and jump up and down and stomp and hug my boy and then scream and cry and stomp and yell some more.
Because I was ready with a whoooooole long list of why's for him.
I was ready with Auntie G- is in love and we want her to love the best person. And sometimes girls marry girls and sometimes boys marry boys. And sometimes boys marry girls. And to us, it doesn't matter because we just want the best people to get married.
And on and on and on and on...
And NONE..NONE of it did I have to explain to him.
He just ACCEPTED my simple answer and moved on to other things.
Why? WhY?  WHY???? Can't ADULTS DO THIS?
We make this world so complicated with our questions and our reasoning and our prying and our stupid stupid judgments and ohhh yes, our power plays.
Why can't adults just accept an answer, a reason, a DIAGNOSIS?
Why?
I am struggling with this.
But amidst it all, I have my beautiful son with his pure heart who just wants to ride his bike and play legos and drink juice boxes and loves his Auntie G- because well, because it's cool she drives a school bus, and he could care less who she's marrying as long as he knows her name.
Thank you Lord for those reminders of what's really important.  No matter what happens, I know the why's in my life, and they are acceptable and right. Even if there are people out there who are still making things more complicated than they need to, I don't need to.
