Making up situational dialogue ~ When did you buy it ?

The theme of today’s dialogue practice was a dialogue containing “glue words.” Based on the course dialogue, I tried to lengthen the situational dialogue and imagine how I would express it under such situation.

A: What’s on the top of the fridge?
B: That’s a bag of rice.
A: When did you buy it?
B: Last year.
A: What ! it has been put too long, it’s already expired, and there are also some rice worms.
B: Sorry, I forgot to put in the rice cylinder.
A: Really wasting food ! This kind of mistake can never be made again.
B: Yes, I will keep in mind.
