It is a long story. I went to visit a friend. I just had a breakup with someone then. I had decided not to go into another relationship for two years. That day, my wife who was a stranger then was passing by and called the attention of my friend who was with me. My friend told me she was his sister. He called her and we exchange greetings and that was all. The funny thing s that that day I knew she would be my wife. My instinct told me.
