People arent JERKS on purpose

My mom always told me that people aren't jerks on purpose but I think Ive found one. This was supposed to be a vent session but the more I think about it and try to understand people, the more it intrigues me. My usual fail safe is to blame everything on low self esteem and parenting, then I learned a new word called Narcissism and it fits this dude like a glove. The type of dude that laughs at his own non-funny jokes and no one thinks he is funny, he gets those few fake chuckles for those few fake people, but are they really fake or just playing a bigger game? The more I think about why people are jerks the more I tend to think that they are reaching out or starving for attention, the attention they didn't get growing up or the attention they aren't getting now. You know the loud guy in the public place yelling into his cell phone about the wild night he had or guy who try's to talk at you instead of to you to make himself look big? Ive come to the realization that when you encounter a jerk , instead of responding to the jerk-ness (shutup) just remember that they are really screaming for attention and on the inside they are little frail individuals who lacked the love and support of loving individuals who care. Once you look at thier life then compare it to your own, you almost have to feel sorry for them. Its a good thing no Jerks read my Posts!
