“I feel like I’m not the same person any more. Do you know what I mean? All my life, when people asked had I any brothers or sisters, I said, Yeah; yeah, I’ve a big sister. Now I’ll be saying, No, it’s just me. Like as if I was an only child.”

“There’s nothing to stop you telling people about her anyway.”

Nora shook her head so hard that her hair whipped her face. “No. I’m not going to lie about that. That’s the worst part: I was lying all along, and I didn’t even know it. Whenever I told people I had a sister, it wasn’t true. I was already an only child, all that time.”

I thought of Rosie, in O’Neill’s, digging in her heels at the thought of pretending we were married: No way, I’m not faking that, it’s not about what people think . . . I said gently, “I don’t mean lie. I just mean she doesn’t have to vanish. I had a big sister, you can say. Her name was Rosie. She died.”

Nora shivered, suddenly and violently. I said, “Cold?”

She shook her head and ground out her cigarette on a stone. “I’m grand. Thanks.”

“Here, give me that,” I said, taking the butt off her and tucking it back into my packet. “No good rebel leaves behind evidence of her teenage kicks for her da to find.”

“It doesn’t matter. I don’t know what I was getting all worked up about. It’s not like he can ground me. I’m a grown woman; if I want to leave the house, I can.”

She wasn’t looking at me any more. I was losing her. Another minute and she would remember that she was in fact a respectable thirty-something, with a husband and a kid and a certain amount of good sense, and that none of the above were compatible with smoking in a back garden at midnight with a strange man. “It’s parent voodoo,” I said, putting a wry grin on it. “Two minutes with them and you’re straight back to being a kid. My ma still puts the fear of God into me—although, mind you, she actually would give me a clatter of the wooden spoon, grown man or no. Not a bother on her.”

After a second Nora laughed, a reluctant little breath. “I wouldn’t put it past my da to try grounding me.”

“And you’d yell at him to stop treating you like a child, same as you did when you were sixteen. Like I said, parent voodoo.”

This time the laugh was a proper one, and she relaxed back onto the bench. “And someday we’ll do the same to our own kids.”
