A Fidel And His Leftovers

His fore finger was once again on the button of an electric bell The Fidel listened to the same old voice "Who is there? " "It's me, but the doors are locked." She opened the door and came out. A girl in her teens! He wonders, what has happened in the last twenty years? When last time his fore finger was on the same button, He heard some other words. "Who is there? " "It's me." "Please come in the doors are open." He always left something at her flat for want of a reason to come back again. Everything has changed during his twenty years exile. But the real change was in that a woman who should be fifty was appearing a teen aged girl! Anyhow, he got in. An old woman came out from the bed room. "So you have come back! Last time when you left the flat You left your something valuable for me. Your son has now started coming here and he leaves something for coming here once again. Tell him who is she? Now you may go, she is a student of medicine, if you have courage to speak the truth tell her who are you and who your son is for her." The Fidel left the flat without leaving anything there!
