Pressing the sandwich flat with one hand, Sarah pinches the tongue of bacon hanging out between its layers and drags the meat from its casing. ‘It’s best not to think about yourself,’ she says, flipping it onto my plate. How generous, I tell her. She licks a grease spot from her fingers and wipes her hands under the table. ‘I love the taste but I can’t stomach the responsibility.’ I didn’t ask for this, I tell her, watching the bacon encroaching on my eggs. ‘I know,’ she says, ‘but you’re a stronger person than I am. You’ll handle it.’
