There was a married couple who lived in rural area of Spain. Their house was a modest little cottage, but it was located on a dangerous, busy main road. The couple had two daughters, twin girls.

As they grew up, the twins were happy and peaceful. They played happily together, never argued and both hated to be separated from their other sister.

One day, the mother had to go to the shops, while her husband was at work, to buy some bread and milk. She didn't want to leave the two girls on their own, so she brought them with her, holding them both by the hand as she lead them across the busy road.

Unfortunately, the mother had forgotten to look both ways before crossing the main road. Just as they were close to the other side of the road, she heard a loud screech and then a terrible crunching sound as both her daughters' tiny hands were ripped from her grasp.

When the mother turned round to look, she screamed in horror and collapsed on the sidewalk. The twin girls had been run over by a truck, and their bloody remains were splattered across the road. She would not stop crying when she saw them. Try as she might, she couldn't tear her eyes away from the huge red streaks on the road.

At the funeral, the father tried to comfort his wife, but she wouldn't listen. She was sobbing hysterically, saying over and over again, "This is all my fault! This is all my fault!"

Four years later the couple were still living in the cottage by the main road. The mother became pregnant again, and was slightly surprised when she was told that she would be having twins again.

The mother and father rejoiced when the girls were born, and the mother even seemed to forget the tragedy of the past with the twins around.

One day, the mother had to go to the shops, while her husband was working. She took the girls with her, and held them by their hands as they walked up to the main road.

Suddenly, as the mother began to cross it, the twins began to struggle and tried to get out of their mother's grasp. "No, Mummy, don't hold us!" the twins cried in unison. "We don't want to die again!"
