One fine day, an old couple around the age of 70, walks into a lawyer's office. Apparently, they are there to file a divorce(离婚). Lawyer was very puzzled. After having a chat with them, he got their story.

This couple had been quarreling all their 40 years of marriage. Nothing ever seems to go right.

They hang on because of their children, afraid that it might affect their up-bringing. Now, all their children have already grown up, and have their own family. There's nothing else the old couple have to worry about. All they wanted is to lead their own life free from all these years of unhappiness from their marriage, so both agree on a divorce.

While they were signing the papers, the wife told the husband. “I really love you, but I really can't carry on any more, I'm sorry.”

"It's OK, I understand." said the husband.

Little did she know that, over the years, the husband has been trying all ways to please her. Little did she know that drumsticks were the husband's favorite.

Little did he know that she never thought he understands her at all. Little did he know that she hates drumsticks even though all he wants is the best for her.

That night, both of them couldn't sleep, toss and turn, toss and turn. After hours, the old man couldn't take it any more. He knows that he still loves her, and he can't carry on life without her. He wants her back. He wants to tell her he is sorry. He wants to tell her, "I love you."

He picked up the phone, started dialing her number. Ringing never stops. He never stops dialing.

On the other side, she was sad. She couldn't understand how come after all these years. He still doesn't understand her at all. She loves him a lot, but she just can't take it any more. Phone's ringing, she refuses to answer knowing that it's him. "I want to keep it this way, if not I will lose face. "She thought. Phone is still ringing. She has decided to pull out the cord(线).

Little did she remember he had heart problems.

The next day, she received news that he had passed away. She rushed down to his apartment, saw his body, lying on the couch still holding on to the phone. He had a heart attack when he was still trying to get through (接通) her phone line.
