Paste

"What's in the sandwiches?" she asked, and he said "Paste", and after a minute or so of waiting for him to elaborate she said "What kind? Wallpaper?" Chewingly he answered with a question: "What do you know about wallpaper paste? We've never redecorated since you were born." And that was true, the house was faded almost to grey. She peeled up one damp slice that left a layer of itself clinging to the paste like a half-stripped wall. Sniffed. "I think it's fish." He shrugged. It was the jar they had left at the back of the fridge, label soaked off. He hoped it was fish, if that's what it smelled of.
