So I talked to my 13 year old sister. I asked her what she does on the internet. She says she has an e-mail account where she e-mails a few of her friends occasionally. She doesn't belong to any social networks, though. So basically, I have no concerns for her safety on the internet. I asked her if her friends did anything she was concerned about. She said sometimes people put dumb things on the internet. But I don't think she was referring to unsafe things, just things nobody cares about. I asked her what she would say to someone who was being unsafe with the internet. She said she would tell them to get a life. I tried to explain the difference between dumb things and unsafe things, but I don't think the distinction is important to her.
Then my 16 year old sister joined the conversation. She said, "Oh, the internet is full of creepers." She refuses to get facebook even because she is so worried about creepy people. I told her she doesn't need to get facebook or anything if she doesn't want to, but I explained that there are safe ways to use social networks and unsafe ways to use them. She had a good idea about posting profile pictures. She said to post a group picture so someone wouldn't know which one is you. I said that was a good idea and also told her about the ideas we discussed in class. I said that in today's world, we really can't and shouldn't avoid using the internet, but we should be smart about it.
