Mi Novia Se Me Esta Poniendo Vieja. (song) Wonderful Spanish song written by a wonderful man about mothers. Mi novia se me esta poniendo vieja (My girlfriend is getting old on me) is amazing and touching. http://www.youtube.com/watch?feature=player_embedded&v=LH1VLXKNIuY#! English translation: She has been my girlfriend since I can remember The good kind of love from when I saw her. I already had a space in my notebook For painting her name and showing off She loved me when beside the finishing line I came last but one in the marathon. She loves me whether insensitive or a poet A genius, a minister or a buffoon Chorus: { My girlfriend is getting old on me And it is a bit difficult for her to walk. Three months without coming over and she Serves another coffee on a tray for her love My girlfriend is getting old on me And I who was beginning to fall in love With the weight of the things that she advises With her universal gift of forgiving } She is my girlfriend and does not blackmail Nor set rules of fidelity. She played cupid for me to every person Regardless of exclusivity She loves me the same whether I go as a guerrilla Or win the Nobel Peace Prize. It is the same to her whether I come last or first Whether I am conformist or stubborn {Chorus} My girlfriend always has a place set In case some day I think about coming back And she prepared a fund (lit: budget) in the bank In case it might be needed some day There is no curve that would distance me from my girlfriend Since there never was a ‘maybe’ on her lips And although the analogy is so obvious You will know that I am talking to you alone Mom
