Internet

I think the internet is a magnificent invention, with which we can find information of everything, talk with people all over the world, and so much more, but it is also dangerous because you don't know people who can put you in a bad place or bully you, and worse, they can find your personal information. 

So internet has many positives and many negatives things, but to make it a safer place we must use it with care, and we must know very well the places that we use, and especially we should not trust people who we don't know.
