Conversation before we went out for dinner on Saturday evening.
N: Are you ready?
D: Yes, I'm not changing my clothes - let's go.
N: Are you going to put your sweater on the right way?
D: What do you mean?
N: Your sweater has been on inside out all day. Maybe you should fix that before we go.
D: All day? Why didn't you tell me before?
N: I don't know. I guess it didn't matter before.
