What I can do on the Internet when I'm home, but I'm at a friend's house? Should I go by my parents' rules or do whatever my friend does?

Stick to your parents rule-no matter where you are, stick to your parents rules because those rules are there to keep you safe. those rules may seem annoying and useless; but theyre there to keep you safe online. if you break those rules you may accidently download viruses or trojans or worms, or you could end up being online bullied. so be careful and just stick to the rules and site you know. if you go somewhere where the rules are different to they are at home. follow those rules because those rules are there to protect the computer from being damaged.
