Your conviction is wrong. Rather, our kids are exploring the virtual social world with an unlimited option. Moreover, they are making their friends around the world. They can also reach to every corner of the world for searching a friend. Nowadays, they are more intelligent: can face the virtual world's problems with guts: they are more aware about their responsibility and duty. The conventional social interaction has some limitations whereas, the virtual social interaction needs a less physical presence rather it is a great fun for our life. It is saved for our kids, if they use it wisely.
