|Why not try this...|
- Download a free trial version of some logging software.
- Use it to capture some activity - website addresses, key strokes, screen captures, etc. A little bit of everything that the software allows.
- Walk into your son's room and present him with the evidence that you are "watching him".
- If you want, make up a little white lie - "Son, I just wanted to let you know, because I love you, that I'm monitoring your computer activity in real time. Here's what I saw the other day."
- Leave the reports on his desk and walk out.
- Close the door to shut out all the screaming he will now be doing.
Mission accomplished at no cost to you!
