What will you do if your child.....

I would be asking myself why am I looking at adult sites in the first place? They're bad news for adults as well as children. If you don't want your children to see these sites, don't go there.

Luckily that's one situation I won't need to consider, since it will never happen. As a responsible parent, I don't visit websites with my kids around that I feel are inappropriate for them to view. If I do have to visit a site with adult related content, I would do it once they're in bed, or in school, and I always shut down all browser pages on the computer when I step away from it, and throw it on standby, simply for the health of my PC.
