Trouble with Teenagers

Why is it that when you talk to a teen about what you feel is good sound advice, they do not listen. I just don't get it. My Father was right when he said experience is the best teacher and a fool learns by no other. Getting back to my story on what happened last summer. The family that my daughter was practically living were being evicted. She was very upset because she had fallen for the young man that was taking care of his brother's young children. At every chance that I had , I tried to talk the young man into leaving that home and to move into another place. My advice was falling on deaf ears. Now they were moving away and my Daughter was heart broken. I was grateful that the lord had see fit to answer my prayer. So it was that last August that family moved out and I was hoping that my Daughter and I could get back to normal. Little did I know that her life had changed forever. She began to think that she was pregnant, even though she was using birth control. The young man was the father and he was gone . She had no phone number, no forwarding address no nothing. We went and bought a pregnancy test. The test was positive, I called my gyn. and made an appointment.
