No you can't.
Unless they post on your wall or tell you - you'll never know. The "See who viewed your profile" applications on Facebook are fake scams in attempt to steal your password - report them to Facebook.
nope
it means to tell them about it
not unless they write on your wall no
I guess that you will be able to tell by how they speak to you!
No but they will know that your on a mobile
Yes. You can't do anything with them. Nothing.
No Facebook will not tell your parents about your account, but they are able to search for it even if they don't have a facebook unless you change your privacy settings. Be careful though because if you are friends with someone who may know your parents they may tell them and then you will get caught.
Facebook would send you an e-mail explaining
There is no way to know unless they leave a comment or write on your wall.
There is no way to tell if someone looked at your social networking page. This goes for Facebook, Myspace, and all of the other forms of social connections.
It doesnt matter what age they/you are, if the other person is saying no to you about posting a picture of them on facebook, that's illegal.
