Internet safety

When you’re on the internet you mustn't ever show

Your home address or real name to people you don't know.

You must keep your computer passwords secret all the time

You mustn't tell me yours and you mustn't ask for mine.


You must remember, be polite to people that you meet

You mustn't treat them differently from people in the street.

And if you feel uncomfortable at something someone's said

You mustn't keep it secret, tell a grown-up friend instead.


What else must and mustn't you do when you're online? Tell us your ideas!
