I'm sitting in the dressing room while Tallulah and my mum try on dresses. I've already found the perfect dress, so I'm now refreshing my emails every two minutes to see if my sister has replied.
My phone rings and I answer it on the first ring.
"Aileen?"
"Aurora, you wanted to talk to me."
Finally, my sister has called me.
"Did you get my email?" This is perhaps the most awkward conversation we've ever had.
"Yes. I've read your email. Aurora..." She stops. "Aurora, this isn't something I want to talk about."
"Is this why you aren't talking to Mum and Dad?"
"Aurora," she's exasperated as if this is a waste of time, "you were always so good at doing what they asked. I wasn't. I used to be jealous of you."
"Why didn't you tell me?"
"Tell you? Tell you that I got knocked up? How am I supposed to tell my perfect big sister that I f*cked up, yet again?"
"Ali," I sigh, "you can tell me anything. Sometimes I need you too, you know."
"Yeah right."
