Topic: Should teenagers spend free time on Facebook?Write a short paragraph to give your ideas.

In my opinion, teenagers spend too much time for Facebook. I have seen a lot of the children use smartphone all day. They don't leave out room. They don't talk anything. But their dad and mom advice them not to use less smartphone. Because they do, too. Facebook is very dangerous enviroment for children but they don't know about it. I think, we should'n spend free time for facebook or smartphone. We can play with friends, hang out,...in order to pratice health, be happy. It is my opinion, about you?
