You were an ordinary student. As usual, you walked in the streets and waited the bus to come. But when the bus comes, a woman suddenly appears and hugs you. When you saw her face... it's impossible: it's your mother who were dead years ago. She was young and seemed to recognizes you:

My dear child... I can't believe it! It's really you! I... I missed you she said with teary eyes.

Have no regrets and enjoy the present moment and every moment with the dear people in your life...
