Ok, so my dad asked me to please stop smoking pot at least until i me and him spoke to a doctor. A couple of weeks later my dad found a little bottle of Visine (i actually do get red eyes once in a while) and has since then never trusted me again. True, i have lied to him before, but now he has no reason to spy on me. I really don't want him to find out about what my girlfriend and I do, and I want to be able to talk to my friends about anything without feeling watched. He's doing this through a program that allows him to see the text i have written on MSN messenger. Is there any way of blocking this???
