Sometimes people talking about how dangerous knives are makes me wonder if they are just talking because they can. I mean I consider irresponsible parents way more dangerous to their kids. I think people sometimes are just plain lazy and rather than take the time to do things right they seem to say something is dangerous and just ignore something that sooner or later they are going to have to deal with.
For example I was a pyromaniac when I was young, and rather than have someone explain to me why fire is dangerous, they just hid the matches. Soon after I found them and I did some dumb things, all because rather than let me play with fire under a supervised condition I had to do it by myself. Luckily no one got hurt.
