No matter what you think, somebody is always watching you. And everyone will notice you at times, the way you die is one of the ways people would notice you. And there's one thing about humans one must take into consideration, and that is curiosity. Some people are just too curious and often they'll go beyond the "i wonder why he/she did it" question and go to more "i wonder how it feels" questions. And this works especially well on kids since not once did a kid repeat what he saw, bad or good alike, he can't tell yet. A parent knows that he cannot watch over his kid all the time so there always is a window where the kid can do something stupid. Also remember that every little thing can provoke a chain of events good or bad. Maybe some of you will not give any notice to what i just said, maybe some of you will say that i don't know what i'm talking about, what i ask of you is to give this a thought, your own thought and care for those around you, because we're all humans after all.
