UPI: A California father says he discovered his 13-year-old daughter sent 484 text messages per day last month -- one message every 2 minutes of every waking hour.

Greg Hardesty of Silverado Canyon, Calif., told the New York Post his 440-page cell phone bill revealed his daughter Reina had sent an astonishing 14,528 text messages.

"First, I laughed. I thought, 'That's insane, that's impossible,'" said Hardesty, 45, a reporter for The Orange County Register. "And I immediately whipped out the calculator to see if it was humanly possible."

Hardesty said Reina had messaged a core of "four obsessive texters," all girls between the ages of 12 and 13. Luckily, he was on an unlimited text messaging plan or his bill would have been $2,905 at a rate of 20 cents per message, the Post reported.

Hardesty told the newspaper he and his ex-wife have placed restrictions on Reina's cellphone use, ruling she cannot text after dinner.
