"It's hard -- every day is a negotiation," she added. "But cigarette smoking I'm not very fond of -- for anyone."

"To my children there's mostly the one who says, 'Have you done your homework?' and 'Why are you wearing that?' and 'Why did you say that?' and 'What are you eating that for?'" she said.
