Two men are drinking at a bar.
A: Have a drink.
B: No. I decided to stop drinking for one year.
A: Is that right? You of all drinkers. You drink day and night.
But the next day, this man appeared at a bar.
A: Hey, you said only yesterday that you had stopped drinking.
Have you broken your promise already?
B: No, I’ve extended my no drinking period from one to two years
and decided to drink only at night.
A: Then, why don’t you extend it to three years and drink day and night?
