She went on about her business, heading toward the kitchen to return the insulin. The minute she left the room, I hung my head down between my knees. They say it's impossible to faint while you're doing this, but I've managed it more than once. I glanced at Ori, apologetically. She was moving her legs restlessly, unwilling, as usual, to concede that anybody might feel worse than she did. I was trying not to hyperventilate. The creeping darkness receded. I sat up and fanned myself as if this was just something I did every day.

"I don't feel good," she said. She scratched at her arm, her manner agitated. What a pair we made. Apparently her mythical rash was acting up again and I was going to have to make a medical evaluation. I sent her a wan smile, which I could feel turning to perplexity. She was wheezing now, a little mewing sound coming from her throat as she clawed at her arm. She looked at me with alarm through thick glasses that magnified the fear in her eyes.

"Oh Lord," she rasped. "It couldn't..." Her face was ashen, swelling visibly, hot pink welts forming on her neck.

"What is it, Ori? Can I get you anything?" Her distress was accelerating so quickly I couldn't take it in. I crossed to the bed and then yelled toward the kitchen. "Ann, could you come in here? Something's wrong."

"Be right there," she called. I could tell from her tone I hadn't conveyed any sense of urgency. "Ann! For God's sake, get in here!" Suddenly I knew where I'd seen this before. When I was eight and went to Donnie Dixon's birthday party next door. He was stung by a yellow jacket and was dead before his mother reached the backyard.

Ori's hands went to her throat, her eyes rolling wildly, sweat popping out. It was clear she wasn't getting air. I tried to help, but there was nothing I could do. She grabbed for me like a drowning woman, clutching my arm with such force that I thought she'd tear off a hunk of flesh.

"Now what?" Ann said.

She appeared in the doorway, wearing an expression that was a mix of indulgence and irritation at her mother's latest bid for attention. She paused, blinking as she tried to assimilate the sight before her. "What in the world? Mother, what's wrong? Oh my God!"

I don't think more than two minutes had passed since the attack began. Ori was convulsing, and I could see a flood of urine spread along the bedding under her. The sounds she made were none that I had ever heard from a human being.

Ann's panic was a singing note that rose from low in her throat. She snatched up the phone, fumbling in her haste. By the time she had dialed 911, Ori's body was bucking as if someone were administering electric shock treatments.
