I always keep things secret when I go online.
I never share the things that should be only mine.
My email and my home address, my phone number and name— These are things only I should know on websites or in games.
And so I use a nonsense name for my net identity.
When folks online ask who I am, I say, “I’m Cyber Me”.
And if I ever think that someone online isn’t all that bad.
I never ever meet them without telling Mum or Dad.
