ATLANTA -- When it comes to teens and texting, how much is too much?
"I text my friends, I text my family, as I'm riding passenger in a car, I text street signs," said Austin Wierschke, a junior from Rhinelander, Wis. and winner of the 2012 U.S. National Texting Championship.
"I've walked into walls, people, a door, lockers, just like not paying attention," said Mary Richard Weiss, a junior at Walton High School in Marietta.
Mary Richard Weiss admits she texts constantly while in school.
"Probably most of the class periods, like all day basically," she said.
Her mother admits she doesn't like how much time her daughter spends texting.
"It is hard to hear (about her daughter texting in class). The e-mails and calls from her teachers. It is upsetting," said Jenny Long, Mary Richard's mother.
