A round of bread
A round of bread is like the loneliest piece of bread you've ever seen. It's just one piece from a loaf. But if you're really lucky, it can also be a sandwich that's so basic, it's barely worth eating.
I asked for a round of bread and got a sandwich that tasted like regret.
My mum said, 'You want a round of bread? I’ll give you a whole loaf and a curse.'
The waiter brought me a round of bread and called it a sandwich. I called him a liar.
