After they'd both gone to bed I remembered that I hadn't drunk the second bottle, so I opened that. I sat on the sofa and watched television with the sound turned down really low so they wouldn't hear it. I can't remember what I was watching, but at some point I must have felt lonely, or happy, or something, because I wanted to talk to someone. The need for contact must have been overwhelming, and there was no one I could call except for Tom.

There's no one I want to talk to except for Tom. The call log on my phone says I rang four times: at 11:02, 11:12, 11:54, 12:09. Judging from the length of the calls, I left two messages. He may even have picked up, but I don't remember talking to him. I remember leaving the first message; I think I just asked him to call me. That may be what I said in both of them, which isn't too bad.

The train shudders to a standstill at the red signal and I look up. Jess is sitting on her patio, drinking a cup of coffee. She has her feet up against the table and her head back, sunning herself. Behind her, I think I can see a shadow, someone moving: Jason. I long to see him, to catch a glimpse of his handsome face. I want him to come outside, to stand behind her the way he does, to kiss the top of her head.

He doesn't come out, and her head falls forward. There is something about the way she is moving today that seems different; she is heavier, weighed down. I will him to come out to her, but the train jolts and slogs forward and still there is no sign of him; she's alone. And now, without thinking, I find myself looking directly into my house, and I can't look away. The French doors are flung open, light streaming into the kitchen. I can't tell, I really can't, whether I'm seeing this or imagining it—is she there, at the sink, washing up? Is there a little girl sitting in one of those bouncy baby chairs up there on the kitchen table?

I close my eyes and let the darkness grow and spread until it morphs from a feeling of sadness into something worse: a memory, a flashback. I didn't just ask him to call me back. I remember now, I was crying. I told him that I still loved him, that I always would. Please, Tom, please, I need to talk to you. I miss you. No no no no no no no.

I have to accept it, there's no point trying to push it away. I'm going to feel terrible all day, it's going to come in waves—stronger then weaker then stronger again—that twist in the pit of my stomach, the anguish of shame, the heat coming to my face, my eyes squeezed tight as though I could make it all disappear. And I'll be telling myself all day, it's not the worst thing, is it? It's not the worst thing I've ever done, it's not as if I fell over in public, or yelled at a stranger in the street. It's not as if I humiliated my husband at a summer barbecue by shouting abuse at the wife of one of his friends. It's not as if we got into a fight one night at home and I went for him with a golf club, taking a chunk out of the plaster in the hallway outside the bedroom. It's not like going back to work after a three-hour lunch and staggering through the office, everyone looking, Martin Miles taking me to one side, I think you should probably go home, Rachel. I once read a book by a former alcoholic where she described giving oral sex to two different men, men she'd just met in a restaurant on a busy London high street. I read it and I thought, I'm not that bad. This is where the bar is set.

EVENING

I have been thinking about Jess all day, unable to focus on anything but what I saw this morning. What was it that made me think that something was wrong? I couldn't possibly see her expression at that distance, but I felt when I was looking at her that she was alone. More than alone—lonely. Perhaps she was—perhaps he's away, gone to one of those hot countries he jets off to to save lives. And she misses him, and she worries, although she knows he has to go.
