2 . Twelve-year-old Catherine has a lot of friends—632, actually, if you count up her online friends. And she spends a lot of time with them.

But is it possible that Catherine’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.

Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not words with friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.

Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platform.

In fact, in many ways, online communication can make friendships stronger. “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.

Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual world, we will have little time for our real-world friendships,” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need anyone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.
