To avoid/ignore/not notice the main part of a conversation, topic ect.

Originating from presumably by someone putting away shopping, and a loaf of bread falls out the bag and to the floor. But the person does not notice it/ignores it and continues to put away the shopping.
"Don't leave the bread on the floor."

"Well sorry I left the bread on the floor."

"I'm afraid you left the bread on the floor."

"Are you leaving the bread on the floor?"
