Bobby, Doctors don't date patients!

Bobby and Mary had their yearly physicals yesterday and every time we visit Mary's doctor, she reminds me of when Bobby was 5 years old and Mary was just a baby.  We rushed Mary in with a fever and the poor thing had a TERRIBLE ear infection....Bobby looked at the doctor, his eyes welled up with tears and he said, "How can this be? We take such good care of her!"  (that was back before he started beating her into submission and perfected the art of the head lock).....Our hearts melted...The doctor remembers that still to this day.  Now, here we are at 13 and 8 and she has brought that up at EVERY visit for the last 7 years♥..........Well doctor, I'm sorry but, Bobby isn't 5 years old anymore and Bobby has raging hormones and I can not be held responsible for this one, cause you should know better than to tell a 13 year old boy that he is good looking! This last time is what I believe will be the end of her conversations with my boy. She began by telling Bobby how cute he was back in those days and then went on to tell him that he has grown into a VERY good looking young man....Innocent enough, right??  WROOOONG!!!  Bobby winked at her and said, "What are you doing on Friday night? (with an arrogant confidence) You ARE hitting on me, RIGHT????"...OMG.... YIKES!...kill me....I sunk so deep into my chair that I could barely see out of the top of my coat.....AGAIN,  a lasting impression....Thank you Bobby!  Where did I go wrong?....I read parenting books!....I studied the statistics!....I tried real hard, I swear I did!......... WHY WHY WHY??????
