Happiness turns to __?__

I was mad.
No, more frustrated - grading quizzes and they really suck (not my quiz but how the kids did).
My hubby tries to cheer me up.
He sees me eying his skin - I have a pen - he says "You want to draw on me?"
YES
I'm blissful!
The kids come in.
Daddy's back is showing and I imitate drawing on his back and the kids want to draw now.
They do...
They are now ecstatic!
They ask us to draw on their feet and toes.
(I am accustomed to doing that to them - they'd make up "toe shows" - we're too poor for puppets)

The joy continues...
Daddy makes a boy face on the bottom of the boy's foot.
The boy asks me to make a mom on the other - so I draw me.

Here is when we become embarrassed...
The boy pushes the bottoms of his feet together and says "They're kissing"
He follows that with vim...he moves is feet into the horizontal position - the drawn faces still touching..."guess what they're doing now?"

Horror
Shock
Embarrassment

"They are having the 's' word"

We started a talk...
There will be more tomorrow.

Have we had an audience?
