Please answer the following question: On Christmas morning, I went to the Cockhedge Mall. People there were all busy buying their last minute requirements. I needed to buy a birthday card for my son-in-law whose birthday is the 29th of December. Picking up a few more things as well as my cared I went to join the line for the express checkout which was for people who only had a few items in a basket and not a trolley load. This line was next to the Customer Service desk. Seemingly waiting quite a long time, I was jogged out of my thoughts by a voice behind me making comments on the things I bought. It was so funny when I realized that she was describing the contents of my basket. The owner of the voice was a very pretty young lady. I said to her that I was going to buy a box of Christmas cookies but the only ones left were not to my liking. The lady told me that just opposite Cockhedge in Superdrug they had lots of cookies. I said, "I'm not going to bother now. I had enough of shops and I'm going home." The assistant from the Customer Service came across at this time saying "If there is anyone in the line with a few items in their basket, none of which needed to be weighed, I will check out their groceries at the desk." Because I had the sprouts which needed to be weighted, the young lady accepted the offer and walked away waving goodbye. Eventually my turn came at the checkout. I was walking away when I met my new friend once again who handed me a beautiful box of Christmas cookies. With a big hug she said "Hope you have a lovely Christmas." She had been into Superdrug to buy me the cookies while I was still queuing in Cockhedge. What a generosity to a stranger! I was so surprised you could have knocked me down with a feather. My Good Samaritan would never know what a joyful Christmas day I had with my family. Telling them this story, as we ate around the table, kept everyone _ What can we learn from the story? A) Nobody is sure what will happen the next moment. B) A simple action can bring other people happiness. C) Being patient will decrease the waiting time.
