She'd wake up early, turn on her laptop and chat on Internet dating sites and instant-messaging programs - leaving her bed for only brief intervals. Her household bills piled up, along with the dishes and dirty laundry, but it took near-constant complaints from her four daughters before she realized she had a problem. "I was starting to feel like my whole world was falling apart - kind of slipping into a depression," said Carla. "I knew that if I didn't get off the dating sites, I'd just keep going," detaching herself further from the outside world. Toebe's conclusion: She felt like she was "addicted" to the Internet. She's not alone. Concern about excessive Internet use isn't new.

"There's no question that there're people who're seriously in trouble because they're overdoing their Internet involvement," said psychiatrist Ivan Goldberg. Goldberg calls the problem a disorder rather than a true addiction. Jonathan Bishop, a researcher in Wales specializing in online communities, is more skeptical. "The Internet is an environment," he said. "You can't be addicted to the environment." Bishop describes the problem as simply a matter of priorities, which can be solved by... Options: A Her daughter's repeated complaints. B Fatigue resulting from lack of sleep. C The poorly managed state of her house. D The high financial costs adding up. Answer: A Her daughter's repeated complaints. Question:
What eventually made Carla Toebe realize she was spending too much time on the Internet?
