Why Won't They Leave me Alone?

I really do love children.  I work with them for a living and it is tremendously rewarding.  I also hope to have children of my own someday.  Children are our future; they are innocent, pure, and sincere.  They have nothing but love in their hearts.  However, when I feel like listening to my iPod and reading, they annoy the crap out of me.  For some reason I have a tendency to welcome the likes of attention-starved children.  While sitting in a waiting room, a hyperactive child kept approaching me, with a desire to show me every object from her mother's purse.  She slowly, stealthily creeped over to me, like a hunter sneaking upon its prey.  Then, if I looked up, she stared for a moment, shocked, and then proceeded to identify all of her mother's personal items.  If I am waiting in a grocery store line, and there is one sitting in the cart in front or behind me, they are constantly staring, smiling, and waving.  I was recently sitting on a plane, again, just trying to read a book, listen to my iPod, and essentially mind my own business.  A little girl in front of me persisted in poking her head through the partition between the seats, smiling.  When I attempted to just ignore her, she had the audacity to tap on my tray table.  Of course, I had to respond, in a smiling, sing-songy voice and comment on her Tinkerbell shirt and her Disney Princess shoes.  

Many times, when parents are bright enough to bring their other children along to an appointment for a child for whom they are concerned, the siblings do everything in their power to get my approval.  I can convince the siblings to do anything, like throw away trash, pick up the blocks that their brother/sister threw across the room, and even provide a medical history.  After I have evaluated their brother/sister, these poor kids will actually follow me out of the room (although I'm the doctor, I am actually a stranger), and tell me many private details of the home situation and their lives.  At the end, when it's time to say goodbye, these poor kids don't want to leave.  When I finally convince them that I can't be their mother and that their family may actually prefer that they return home, the kids are pretty adamant about kissing, hugging, etc.  I have a rule that I don't really like to touch other people's children, without some blood relation or need for a medical examination.  Many of my patients like deep pressure on their mouths, and are very aggressive about climbing on me, hugging me, and pressing their dirty little mouths against my face.  Being the obsessive-compulsive germaphobe I am, there are times when I have to leave the room so I can stop hyperventilating from the anxiety.
