Объяснение:
It was a few years ago when I was 22. I fell in love with a girl from my major, but she did not show any signs of interest in me. I thought that I was not good enough or she loved somebody else. I just tried to be a good friend and supporter as I did with almost everyone. However, once, we accidentally stayed together after classes, and she told me that she noticed my interest and she had the same feelings for me. This day became the start of our relationships that have been continuing still. Now she is my wife, and we love each other.
