I was working on some statistics the other day when the cleaner arrived. I left the work on the screen, and when she walked by, she noticed the mathematical formulae.
"You are mathematic?" she said.
She is not entirely fluent in English.
"You are a teacher?" she said.
"No, not a teacher," I said.
"But you are mathematic?" she urged.
"Yes," I said.
"I am economic," she said. "I study in Poland."
The boy sees me reading a history book. He has keenly noted my predilection for things past. He sits with me when I watch TV programmes on ancient civilisations and disappeared empires.
"I want to be historic, like Acha," he says.
"Not pre-historic, like the dinosaurs?" I tease.
"Stop it, Acha," he says.
