It was 9:00 am already! Richard had to leave for work! Before leaving he hurriedly looked at the newspaper and stood still! Is he seeing it right? He rubbed his eyes and saw again… Yes, it was his name in the obituary(讣告)! He threw the paper in the bin and screamed.

Richard started to recollect. He remembered that last night when he went to bed he had a chest pain and he was rushed to hospital. Then he went into a sound sleep. But what happened after that?

He could suddenly see his living room filled with people… all in tears; his mom, his wife and his children. He also saw his best friend, the one he had a serious misunderstanding a few days back. He wanted to say “Sorry” to him… but now no one could hear his voice.

He wondered how he could tell his mom that he felt so thankful to have her in his life! He wanted to tell his children how much he loved them. He wanted to tell his wife how much he loved her; he felt sorry to have hurt her sometimes.

Richard started crying and pleading to God for one LAST chance! “God, one last chance, please”, shouted Richard and opened his eyes.

Oh, this was a dream!

He woke up; looked around everywhere. He was on his bed; his wife lay beside him, deep in sleep. Richard whispered in her ears, “You are the best thing to have ever happened to me!”

He went up to the window, looking outside. Yes, everything was just the way he has been knowing so long. He decided to meet up his friends and clear all misunderstandings; he also decided to tell everyone who mattered to him all that has remained unsaid so far!
