normal drama and crossing the line

I understand that there are many different kinds of people in the world and that everyone has issues. what i don't quite understand yet is why people feel the need to put others down, stick their noses in other people's business, can't drop issues when they should be or feel the need to start crap with people they don't even know. I realize that there will always be drama and bs in life, but there is a limit and many people seem to cross the line and take things way too far way too often. Even i have gone too far on occasion and i know that, but i stop when i realize that the line has been crossed. To tal k about other people behind their backs, run them down, or post stuff that they have no right to is pretty childish and petty. No matter how old you are you always have growing up and learning to do, but as an adult you should be grown up enough and should have learned enough to not act like a teenager or start petty bs for no reason. I have recently had to deal with these types of issues personally and have had the line crossed by a long shot. We are all supposed to be adults and should be able to act it. People seriously need to use their heads more and grow up. I realize this does not apply to all people for I have met some very decent people who know how to joke around and know when things have gone too far. The people that feel the need to start crap with others and put them down for no reason just to make themselves seem and feel better are fooling no one but themselves and are truly makin themselves look much worse in the long run. Again I realize there will always be issues and drama, but people seriously need to learn where the line of normal bs and being really stupid and ridiculous is. They also need to learn that if it doesn't concern them to stay out of it, especially if the problems have already been dealt with. Serious issues should not be brought up again at a later timeand the bs started again just because someone is bored or feels like starting crap again. People should be able to hang out with friends and joke around and have fun without attention seekers trying to start crap. I know there will always be someone who feels like starting something and the normal bs can be ignored, but for those who seem to need to cross that linemany times I have this to say to you : damn people grow up already.
