Is it possible to monitor a son/daughters Facebook?

[Matthew]

I am 16, but my grandmother was wondering - is it possible to monitor someone's Facebook? For example, lets say that my mom wanted to know what I was doing on Facebook (and I don't mean just looking at my wall/news feed, I mean things like messages - private things) is she able to do so? No by the way, I am not a teen looking for help because I have "gotten in trouble with me mom." Lol, just wanting to know though, thanks!

Yes. They can demand your password before allowing you Internet access. Or put child monitors or a key logger on the computer.

Yes they can if they are smart enough. There are lots of tools available for free on the internet they can install it in your pc and they can know everything even your passwords.
The best part of those tools is that only the persons who installs it can open it with a password and other user won't even know that there is program like that installed on your PC.
