Late night conversations

In the dark, late at night with a quiet house, this conversation occurred between two parents:

"Are you awake?"
"Yeah. What?"
"Sometimes I worry that I'll love one kid more than the other."
"Mm hm. Yeah, sometimes I do too."
"Which one do you think you'll love more?"
"The second one."
"I worry I'll love the first one more."
Long silence.
"Well, that's ok then. It'll be even. 'Night."
"Good night."
