No more "happy returns" needed

It was his sad birthday after she left him.

His eyes show how he couldn't cherish that day,in anyway.

"Many more happy returns of the day", she texted him.

Something uneasy went through his throat to belly.

He could feel his heavy heart.

His vision turned blurry with tears.

He wasn't aware of what he's doing. 

He cleared those teary eyes, he copied the text and Googled its meaning and usage.

He greeted many people without knowing it's meaning.

He's anxious and curious to know,as it was an attempt to worry in the name of his ignorance than to worry in the name of people who left him. 

Google gave its meaning and how it should be used on.

He found its usage as follows.

"Since the 18th century this has been used as a salutation to offer the hope that a happy day being marked would recur many more times."

He read it twice,to understand.

An ironic smile passed over on his face. He laughed out of pity for himself.

First of all,this day wasn't happy anymore and he laughed at her wishes,that conveyed to have such days,many more in his life.

Now his smile sounded very loud and tears streamed down his face.
