A Fine Day

One day a husband randomly says to his wife, “Today is a fine day!”
The next day, he says it again: “Today is a fine day.”
Again the next day, he says the same thing: “Today is a fine day.”
After a week of hearing the same comment, the wife asks her husband, “Since last week, you have been saying today is a fine day. I am fed up. What’s the matter?”
“Last week, when we had an argument, you said, ‘I will leave you one fine day.’ I was just trying to remind you.”
