B: You might be able to. I need a ball of wool that is the same color as my jumper.
A: Just a moment, please. I must look in the stock room. We might have some left. I’m not sure.
B: The wool mustn’t be exactly the same color, it must be different.
A: Could I ask you a question, madam?
B: Yes.
A: What do you want the wool for?
B: I must finish knitting this jumper. It only has one sleeve at the moment!
