A KFC CUP

One day, our family go to the KFC to have dinner.

After the dinner, my mother in law took a glass cup into her bag, which it is belongs to the KFC.

When back home, my husband and my son saw the cup and asked, "Who took this cup back home?"

I shaked my head and said, “It's not me.”

He asked his mother,"Why you took the cup back, we have all kinds of  cups ."

And my son said," It's not ours. We can't steal the cup."

Then, he told his father,"We should return the cup back next day."

I don't know why my mother in law took the cup back home. 

Actully, our home have many kinds of cups for using.

I think it is not a good behavior and I told her need to do a good example for the kids.

If she want to something, we can buy at the shop or supermarket.
