Their party plans had nearly been abandoned because of Mary’s summer cold, which Becky would probably have been OK with, if she’s honest. But now that Mary is on the up, the only sign of her ailment a lower-than-usual voice, left gravelly by a week’s coughing, it’s all back on and they’re arm in arm, walking down the road from Mary’s house, with Mary pushing and pushing to see if Becky will do a pill with her tonight.

Mary is Irish and favours wearing pinafore dresses with band T-shirts rumpled up underneath. She is extremely persuasive. Her hair is terracotta red out of a packet which emphasizes the china white of her skin, which in turn emphasizes the rings of dark under her eyes which are there because she has to get up earlier than her body wants to, she says, which is one more crime that the education system has to answer for. Mary feels that the school week compounds the problem of weekends, which should ideally involve missing at least one whole night’s sleep.

‘So? Are you going to do one with me or not?’

Mary believes that, as friends, you go down together and you come up together. If it’s a good pill then you have a fellow traveller for the night, and if it’s a bad pill then you don’t die alone.

Today, Mary is disappointed about an unsupportive government and disappointed with the bags under her eyes, and Becky can’t quite bear to add to the tally, at least not yet, so she says: ‘Yeah, maybe I’ll take a pill. We’ll see. Yeah, go on then.’

Mary whoops because it is only a party when you are guaranteed to have fun and not die alone. Then she takes out two cigarettes, lights them both and hands Becky one as if smoking cigarettes together is the best way of sealing this deal of togetherness.

It is Saturday night and Becky is feeling good. Her skin feels lit with magpie-bright colours and sparkles, and it fits well. At this moment, walking arm in arm with her best friend, everything is as it should be.

Oh, to have a photograph of that moment, the time before the rest of it happened.

To have that to come back to, to tell yourself: you are still in there, that girl with flying hair and a newly lit cigarette and a whole weekend, a whole life, laid out for the taking. She is not lost to you. Imagine yourself back into that skin and feel the closeness of the fit. Persuade yourself.

But you are not watched by anything other than a fat, ginger housecat, which moments after you pass him forgets you for a rat-rustle in the bushes nearby.
