I've often wondered how early, in development, Narcissism begins or if it's a matter of stunted growth. I found myself dealing with a couple of teenaged N's last night, during National Night Out. (I know, I know - teenaged N's is redundant as that is the nature of the beast.)
I'm in the midst of grilling hot dogs and hamburgers, keeping an eye on the fire so that nothing gets overcooked when this one teenager walks up to me and DEMANDS a soda! (Not even a "please"!) I informed her that all we have is water. She huffs, gives me an eye-roll, and walks off. I turn my attention back to the grilling. Then she comes back and DEMANDS juice! I repeat what I said a few minutes earlier: "All we have is WATER!" She huffs, again, gives me another eye-roll, again, and walks off. Then, at the END of everything ... the event is done, we are packing up, loading stuff up in our cars, cleaning up, when Little Miss ENTITLED comes back and gets up in my grill, DEMANDING CHIPS! I informed her that the event is at an end, food service is no longer available, and my group is in the middle of cleaning up. She points to an unopened carton and DEMANDS that I rip it open because she wants chips NOW! I told her: "The event is OVER! Time to go home! I'm busy cleaning up!" I go back to what I'm doing. Then, Miss ENTITLED's elder brother comes over, gets up in my face, and attempts to intimidate me into doing what he and his sister wants NOW! By this point, my patience is DONE!

The only thing these two N's have succeeded in achieving is PISSING ME OFF! I informed them, quite firmly, that THE EVENT IS OVER AND THERE IS NO MORE FOOD! That is when they finally left! Clearly, they have NO manners!
