Internet saftey

I know I learned this in school, but im gonna have to write about it for the student challenge activity 7.  Well internet saftey is really important.  You have to be sure if they are the person your talking to.  If you dont know then maybe it might be a 30 year old man.  If your not cautious about it its scary cause your talking to old people.  So be cautious about who you talk to on the internet and you shouldnt trust everybody on there.
