Technology is doing such fabulous things. I can't imagine being a teenager now. Because while technology is exciting to see as an adult (which I'm afraid I fully qualify as at 36 years old now...), it would have been a lot more fun to use as a teenager. Maybe a big dangerous, even, but fun.
Take for example services for reverse phone tracer. So you have someone's phone number. But you'd really like to know more? Easy peasy. Go to the reverse phone tracer, put in their phone number, and you get the other information from their phone listing. Want to know who called you? That information would be with their listing. Trying to figure out where a number is that appeared on your phone call? Now you can look it up, and they'll never know!
