People Who Need Professional Help Amuse Me

D is a girl who lives in my building. D is supposedly an adult. D doesn't seem to like me, although for the life of me I don't know why. I'm a friendly sort of person....
D never greets me in the elevator in the morning. Moreover, as D pushes passed me to exit the elevator in the morning, she drops the elevator door on me. She then follows up by dropping the main building door on me as well, as we exit the building simultaneously. I've always chalked this up to the fact that perhaps nobody ever taught her manners when she grew up. Perhaps she never had a positive parental role model.....
Today though, D's dysfunction reached an all time high, and although I'm sure she did this to annoy me, she made my day!!!! I overslept this morning and was running late. Jen was in a rush to get to the camp bus stop and refused to leave without me. So Jen went to ring for the elevator as I was collecting my things. The elevator arrived before I did and, just my luck, D was inside. Jen immediately let the door go so that D wouldn't have to wait for my arrival and as the elevator descended, she rang for the elevator again. Wouldn't you know it? D did something I haven't seen since my sons were about 5 years old or so, and trying to annoy each other. D pressed every button in the elevator so that as the elevator returned to the 6th floor to Jen and I, it would first have to stop on each and every floor, thus slowing it's progress. Now, I know that D was trying to annoy me, but I must say that I had an all out belly laugh over it. These are the proud citizens of tomorrow???? These are the "educated singles" in our neighborhood. OK, now granted, most of our singles here wouldn't want to be categorized with D for a host of other reasons, but she really gives young adults a poor name.
But in any case, D, if you're out there THANK YOU!!! You made my day!!!! (... though in all seriousness, I think perhaps you should seek some professional help....)
