One day I went shopping with my son. We went to the supermarket in the new shopping center.
"Why do you buy things here " my son asked me." Because they are cheaper than the shop near our home." I answered, "Help me save money, please."
I wasn't rich and was always careful with my money. I bought lots of the things in the supermarket. When we got home, my son said, "I don't think you saved money by going to the supermarket." "Of course I did." I answered, "Everything was cheaper there."
"We know," my son said, "but we came home by taxi because we had many things. The taxi cost more than the money that you saved! "
"Oh," I said, "next time we'll do the shopping nearby."
