On secrets

A couple of weeks before she left, and in a diminished mental state, my wife used her finger to call me close to her.
As I got closer she whispered.

"I've always been a little bit bi'

On the outside I was like...
It's alright honey, everybody is a little bit bi sometimes.... With that said, I touched her face, she smiled, and we continued watching Family Guy on the Tv mounted on the wall.

Inside I was like...
Whaaat??.. I never saw that coming. Not in a Thousand years.

Made me wonder.

How much do we really know about our partners. How much of their secret places can we see.

The question being...

How much of you , of who you really are, what percentage, do you keep secret from your partner. How much do you think, your SO really knows about the real you??
