“Go fuck yourself John!” Laura screamed. “You’re not here for me, you’re not here for the kids! You never do anything for anyone but yourself!” She snatched her coat and slammed the door.
        The house settled into a sickening quiet in which her words sank deep under his skin.
   Now the sounds of glasses clinking and the heavy throb of the music seemed dull in his ears. He still felt that heavy silence in his bones. He didn't even look up at the dancers. He’d been here so many times they were old news.
        What an insufferable bitch. But was she right? When was the last time he did anything for anyone? He grimaced down at his beer. It tasted bitter. He abandoned it and went out into the night.
   Out here it was quiet, but a soft sobbing suddenly caught his ear. He turned, trying to find the source of the sound. He followed it around the corner of the building, where a young woman sat in the ally cradling her arm, which hung at a very unnatural angle.
        He recognized her as a stripper that had been working earlier in the evening. Now her clothes were back on but her eye makeup was scrawled across her face and her heel was broken.
   “Are you alright?” he asked stupidly.
   She didn't reply, until he asked again. Then she croaked, “He broke my arm."
   He reached over and tried to help her up, despite her angry attempts to shoo him away.
   “You need to see a doctor,” he insisted.
   “Get out of here,” she snapped, then melted into sobs again.
   He hoisted her to her feet, careful of her arm, and hobbled her slowly out of the ally to his car. She let him lead the way and slumped into the passenger seat of his car. The car ride was silent, except for her quiet sniffles.
   “What’s your name?”
   She didn't answer.
   He drove faster. “Everything’s going to be Ok,” he said out loud for the both of them.
   He parked in the emergency lane of the hospital and helped her out of the car, looking down at their feet to avoid seeing the fresh tears on her cheeks.
   At the check-in window she said her name was Sarah.
   He sat in the plastic chair next to her while they waited. She wiped her eyes with a tissue.
   “That’s my daughter’s name,” he said softly.
   “Why are you doing this?” she demanded, looking straight ahead.
   He paused a beat, thinking. “I just want to help. I never do anything for anybody.”
   “Hm.” Her eyes finally slid over to him. After a moment she said, “Thank you.” Then, “Don’t tell anyone, Ok?”
   He blinked. “Why not?”
   She gave a sad chuckle that turned into a wince of pain. “I’m doing you a favor. What are you going to tell your wife and co-workers? That you helped a dirty prostitute?”
   John didn't reply. She was right. “I won’t tell anyone.”
   The nurse called for Sarah and she stood. He did too. “I can wait for you,” he told her. “I can bring you home, or somewhere safe.”
   “No.” She hesitated. “Wait. I guess. If you want to.”
   He sat back down and picked up a magazine. “I’ll be right here.”
   She watched him as if waiting for the punch line of some cruel joke. The nurse called her again. She looked like she wanted to speak, but instead she turned and met the nurse at the door. John stayed in his seat.
        So it was a secret good deed. That was fine. Something inexplicable about it still made him feel different. He felt… good. He didn't care who she was or what she did. She had needed help and he had helped. Even if he had to keep that to himself for the rest of his life, he knew, and she knew. Sitting in that chair and waiting for her, he felt good. Better than he’d ever felt before.

Ooo I like the story. Is he going to become someone who does all this good crap he can never mention?

As for criticism:
1. There's not much transition period between being screamed at and ending up at where ever he was. In fact, until he's outside I was not very clear on where he was and where Laura was.

2. He needs more personality. It's a short piece but he feels a bit 2D to me. Why is he helping? Does he feel bad? Did he turn around that quickly? Turning around that quickly seems unnatural unless it hit him hard, which there's no indication of .

3. The stripper is more interesting to me than the guy. Give him some personality or a little more back story/a few lines/a flaw (what he did to piss Laura off) and he will become interesting .

Hope that helps!
