<human>: My sister, as do most early teens here, has discovered the delights of talking to her friends on Windows Live Messenger. And recently has found the use of the camera at the top of her laptop. Our mum, being not great at understanding modern technology is a bit dubious. Shs's not that worried that she will talk to strangers and get stabbed in a field but she is worried that things she types or does over the webcam can be found and used against her by others. She asked me and I assured her that there is no way that anyone other than the other person in the coversation can see or read anything the goes between them. How much of a lie was that?

Give me the gist of the text in a nutshell
<bot>: I told mum that there is no way anyone can see or read anything my sister does over Windows Live Messenger. How wrong was I?
