It should be common fucking sense.
I'm not gonna lie, I'm pretty hurt and pretty pissed at the same time. Recently, a kid at my old high school committed suicide as a result of bullying. He was an aspiring musician with loads of talent, from what I read and, even though I didn't know the kid personally, it still bothered me. The fact that kids these days have gotten so bad that it pushes others to take their own life... Here's the part that pissed me off; kids were posting Facebook status' about his death saying things like "I'm tired of hearing about it..he was a vagina for killing himself...if I hear about it anymore I'm seriously going to punch someone" and what have you. How the FUCK did this generation become so desensitized to everything? Not to group the generation as a whole, given there are a few kids out there with better sense than this, but what the hell? This generations' gone to hell, as far as I'm concerned.
The whole point to this: in laymens terms, don't be a fucking prick to one another. Overall, watch how you treat people and watch your words. 90% of the time people pay NO attention to what comes out of their mouth, much less how it effects someone and because of it, sometimes this is the (chilling) result.
