To ease the distress of Kathleen’s constant departures, her father had glued a large map of the world to Liza’s bedroom wall. Each time her mother had left on another trip, Liza and her father would put a pin in the map and research the place. They’d cut pictures from brochures and make scrapbooks. It had made her feel closer to her mother. And Liza’s room would be filled with various eclectic objects. A hand-carved giraffe from Africa. A rug from India.

And then Kathleen would return, her clothes wrinkled and covered in travel dust. She’d bring with her an energy that had made her seem like a stranger. Those first moments when she and Liza were reunited had always been uncomfortable and forced, but then the work clothes would be replaced by casual clothes, and Kathleen the traveler and TV star would become Kathleen the mother once again. Until the next time, when the map would be consulted and the planning would start.

Liza had once asked her father why her mother always had to go away, and he’d said, Your mother needs this.

Even at a young age Liza had wondered why her mother’s needs took precedence over everyone else’s, and she’d wondered what it was exactly that her mother did need, but she hadn’t felt able to ask. She’d noticed that her father drank more and smoked more when Kathleen was away. As a father, he had been practical, but economical in his parenting. He’d make sure that she was safe, but spent long days in his study or in the school where he was head of the English department.

She’d never understood her parents’ relationship and had never delved for answers. They seemed happy together and that was all that mattered.

Liza had thought about her mother exploring the desert in Tunisia on the back of a camel and wondered why she needed her world to be so large, and why it needed to exclude her family.

Was it those constant absences that had turned Liza into such a home lover? She’d chosen teaching as a career because the hours and holidays fitted with having a family. When her own children were young she’d stayed home, taking a break from her career. When they’d started school she’d matched her hours to theirs, taking pleasure and pride in the fact that she took them to school and met them at the end of the day. She’d been determined that her children wouldn’t have to endure the endless goodbyes that she’d had as a child. She’d prided herself on connecting with them, and encouraging conversations about feelings, although these days those conversations were less successful. You can’t possibly understand, Mum, as if Liza hadn’t once been young herself.
