Where'd all the good fences go?

We wander along the streets, glad to be out of the house after a weekend of rain.

"I want to walk up there." She pulls herself up onto the low brick wall and streached out her arms to balance.

I walk along the footpath next to her.

"Ooo - I'm so high!"

"Very high - almost as tall as me."

She pauses, grabs me for balance and stands on her tippy toes. "No, I'm higher."

I smile and decide not to disagree.

I hold her hand as she jumps down and runs to the next fence, it's a picket fence so she runs to the next one. It's a high security fence.

"Erin?"

"hmm?"

"Why doesn't everyone has good fences?"
