“Of course!” I say. “Absolutely!”

“But will she still get the credit?” chimes in another friend anxiously. “Because she’s already failed one module.”

“It’s all his fault,” says the first friend viciously, and about ten girls nod in agreement, murmuring things like “It so is” and “Tosser” and “He can’t do a smoky eye.”

“We were together for two years.” The pale girl gives another sob. “Two whole years. I did half his coursework for him. And now he’s all like, ‘I need to focus on my career.’ I thought he wanted to be with meeee.…” She dissolves into prolonged weeping and I stare at her, tears starting to my eyes. I know her pain. I know it.

“Of course you’ll get the credit,” I say warmly. “In fact, I’ll give you a special mention for turning up when you’re clearly in mental distress.”

“Will you?” Cindy gives me a watery smile. “Will you really?”

“But you have to listen to me, OK? You have to listen to me.”

I’m feeling a gathering urge to speak off-topic. To convey a universal truth, not about pensions, not about tax breaks, but about love. Or not-love. Or whatever limbo place we’re both in. I know it’s not in my remit, but this girl needs to know. She needs to know. My heart is beating strongly. I feel noble and inspirational, like Helen Mirren or Michelle Obama.

“Let me say one thing to you,” I begin. “Woman to woman. Professional to professional. Human being to human being.” My eyes fix on hers intently. “Don’t let a breakup ruin your life.” I feel so galvanized. I feel so sure of myself. I’m burning with my message. “You’re strong.” I tick off on my fingers. “You’re independent. You have your own life, and you don’t need him. OK?”

I wait until she whispers, “OK.”

“We’ve all had breakups.” I raise my voice to take in the whole room. “The answer isn’t to cry. The answer isn’t to eat chocolate or plot revenge. You need to move on. Every time I’ve had a breakup, do you know what I’ve done? I’ve taken my life in a new direction. I’ve found myself an exciting new project. I’ve changed my look. I’ve moved house. Because I’m in charge of my life, thank you.” I pound my fist in my palm. “Not some guy who can’t even do a smoky eye.”

A couple of girls break into applause, and Cindy’s friend whoops supportively. “That’s what I said! He’s a waste of space!”

“No more crying,” I say for emphasis. “No more tissues. No more checking your phone to see if he’s called. No more stuffing your face with chocolate. Move your life on. Fresh horizons. If I can do it, you can.”

Cindy is gawping at me as though I’m a mind reader.

“But you’re strong,” she gulps at last. “You’re amazing. I’m not like you. I never will be, even when I’m your age.”

She’s looking at me with such wonder, I can’t help feeling touched, even though she doesn’t have to behave as though I’m such a dinosaur. I mean, I’m only thirty-three, not a hundred.

“Of course you will,” I say confidently. “You know, I was like you once. I was quite timid. I had no idea what I would do in life or what my potential was. I was an eighteen-year-old kid, floundering around.” I can feel my All-Purpose Motivational Speech coming on. Do I have time to give it? I glance at my watch. Just about. The short version. “I was lost. Exactly like you feel now. But then I went on my gap year.”

I’ve told this story many, many times. At student events, at team-building seminars, at preparation sessions for personnel going on sabbaticals. I never get bored of telling it, and it always gives me a tingle.

“I went on my gap year,” I repeat, “and my whole life changed. I changed as a person. One pivotal night transformed me.” I take a few steps forward and look directly at Cindy. “You know my theory of life? We all have special defining moments which set us on a path. I had my biggest defining moment on my gap year. You just need to have your own big moment. And you will.”

“What happened?” She’s agog, and so are all the others. I can even see someone switching off their iPod.

“I was staying at a guest house on Ikonos,” I explain. “It’s a Greek island. It was packed full of gap-year travelers, and I was there all summer. It was a magical place.”

Every time I tell this story, it brings back the same memories. Waking every morning to the Greek sun dazzling my eyelids. The feel of seawater on sunburned skin. Bikinis hung over peeling wooden shutters to dry. Sand in my trodden-down espadrilles. Fresh sardines grilled on the beach. Music and dancing every night.
