It is too strong to be an illusion. Clearly this is something that I have been permitted to remember for reasons I cannot comprehend. And I remember more. I remember her soft gasping sounds of pleasure. I know that my own body did not betray me those three nights, nor did I fail her need.

And there is more. A memory of sinuous music; a scent of youth in her hair; the rustle of winter trees. Somehow she brings back to me a time of innocence, a time when I am young and girls are mysterious, a time of parties and dances and warmth and secrets.

I am drawn to her now.

There is an etiquette about such things, too. It is in poor taste to approach someone you have met while being ridden. Such an encounter gives you no privilege; a stranger remains a stranger, no matter what you and she may have done and said during your involuntary time together.

Yet I am drawn to her.

Why this violation of taboo? Why this raw breach of etiquette? I have never done this before. I have been scrupulous.

But I get to my feet and walk along the step on which I have been sitting until I am below her, and I look up, and automatically she folds her ankles together and angles her knees as if in awareness that her position is not a modest one. I know from that gesture that she is not ridden now. My eyes meet hers. Her eyes are hazy green. She is beautiful, and I rack my memory for more details of our passion.

I climb step by step until I stand before her.

“Hello,” I say.

She gives me a neutral look. She does not seem to recognise me. Her eyes are veiled, as one’s eyes often are, just after the Passenger has gone. She purses her lips and appraises me in a distant way.

“Hello,” she replies coolly. “I don’t think I know you.”

“No. You don’t. But I have the feeling you don’t want to be alone just now. And I know I don’t.” I try to persuade her with my eyes that my motives are decent. “There’s snow in the air,” I say. “We can find a warmer place. I’d like to talk to you.”
