What I did at lunch today

This is a short story written while chomping on my lunch coz well the topic was very interesting. This was in response to a daily/weekly (i dunno) Flash Fiction (under 500 words) Sandbox, at the india writing community at live journal. Now what it is, is that people are given a scenario and they've gotta come up with a story under 500 words and post it there. The scenario that intrigued me into writing this story was,

Flash Fiction sandbox - writing prompt 4- Here's your scenario.Your protagonist has just discovered s/he has AIDS. S/he is meeting her lover in a cafe. S/he must, by the end of the story, have asked her lover to marry her/him. And the lover must accept.You have up to 500 words in which to pull it off.

This was my attempt, whatchu think?

"I've got AIDS", he told her. She choked on her coffee and blurted "Whaat?"

He flicked his cigarette impatiently in the vicinity of the ashtray and repeated "I've got AIDS, I'm HIV fricking Positive".

He turned to the side and fixed his attention at the window.

She was dumbstruck; she felt everything freeze around her. "You, you aren't joking right?" she stuttered.

The morose look on his face gave her the reply his lips were to proud to.

What? How? Who? When? Questions flooded her mind but she knew better than to ask any of those.

She struggled to fight back the tears, suffering the news in silence.

"So the marriage is off or are you still gonna marry me?" he asked as if he was taunting her to reject him in his face.

"Yeaah" she replied dazed.

"Which is it?" He asked.

"I dunno, not really sure what I'm thinking" she replies looking down at her cold cup of coffee "One of the two, I guess".

He shook his head and turned again to the window, angrily flicking his cigarette.

After a pregnant pause, she looked up at him and asked "I need to know more"

He replied "Like what?' without turning.

"Firstly, I want you to look at me when I'm talking to you and secondly, I want you to be FUCKING honest with me and tell me all about it, right now!" She said with eyes blazing

He was shocked, he'd never heard her speak this way and though it angered him he realised that at this point of his life, this was his only chance at happiness, however remote that chance was.

He forced a smile.

"Thank God this place is so crummy that it's empty all the time, eh?" he said nervously, trying to calm her down.

The blazing look in her eyes told him that she was deadly serious.

Slowly he began telling her about his secret life, things that no one knew about him, things he thought he'd take to his grave, things he'd never expect a girl like Priya to even hear.

In the end, he couldn't stop the tears that flowed along with his words.

And when the words ran out, he sat there hunched over with his face buried in his hands.

Minutes wore on and he began composing himself and he looked up only to see her looking at him.

There were tears streaming down her face as well.

"Ok" she whispered.

What?" he quizzed in a hoarsely, not sure of what he was hearing.

"I'll marry you, but remember things have to change!" She said.

"But Priya…" he began,

"What?" she snapped back at him, wiping her tears.

"You don't have to…you shouldn't have to.." his voice faltered.

"I never did have a choice" she replied staring at him resolutely with fresh tears rolling down her cheeks.

He looked stunned.

He felt like he got a glimpse of something profound and suddenly it felt like the earth stopped revolving around him.

He began to see her in a different light, he always thought she was a pushover but now he knew that she was far from it.

He knew what this decision meant for her. She would never be the little girl in her father's house again.

She had blown him away.

"Priya, my darling Priya'" he said , "You're amazing but, but, you see, I can't let you do this, for once I'm gonna do the right thing by you"

He got up, smiled affectionately at her and said "I have to set you free my darling"

He reached forward, patted her wet cheek as she looked at him pleadingly and then turned around and walked away.

(OK I cheated and edited this version since the original I put up seems to have some contextual (my big word for the day) and grammatical (Could you believe even now my first instinct is to spell this word as grammer! Blardy Awful!) errors, now I'm pretty sure this is more than 500 words but what the hey, this ain't for a contest!)
