​SCRIPT

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?
