2020 WAEC English Language Theory (a) Why did the writer’s mother never inform her children of her intention to visit…

Read the following passage carefully and answer the questions on it.
     My mother never thought it necessary to inform any of her children that she would pay them a visit in Lagos at any time. After all, no child would refuse her entry into their home. She had always been lucky to meet a member of the household each time she came Visiting and it was unimaginable to her that a day would come when no one would de at home to receive her.
     In her usual manner, Mama boarded a vehicle from the village at noon with all her luggage which usually comprised the local delicacies we all enjoyed eating whenever she came visiting Since she was aware of the time of the day everyone would be back home from work, she was not worried when the bus made frequent stops to either pick up or discharge passengers. while the journey lasted, Mama chatted heartily with a fellow passenger who was also going to See her son in Lagos and the two exchanged telephone numbers.
    Eventually, the vehicle crawled to a final stop and everyone alighted. Mama flagged down a taxi and headed for her daughters’ house. Although the fare demanded by the driver, was outrageous and the money on her could not cover it. Mama believed that when she got to the house, her daughter or son-in-law would come to her aid by making up the difference.
     How wrong she was! Unknown to Mama, my husband and I had traveled out of town on one of our numerous official assignments while my son had returned to the university campus, The only person on the premises was the new watchman. Mama s dilemma, however, began with the payment of the taxi fare. When she alighted with some of her luggage, she met the cold unfriendly stare of a complete stranger. She tried frantically to introduce herself to the watchman but could not communicate effectively because of the language barrier. To her embarrassment, the taxi driver called her a fraudulent old woman, left his contact number, and drove off in annoyance with one of her bags.
        Mama remembered that the woman with whom she had traveled on the bus had given her her phone number and she decided to call her for help. After what seemed like an eternity, the woman’s son drove in his car to fetch Mama. My mother was quite grateful for that but she will never forget the fact that she had to eat spaghetti and omelette for dinner.
       That night, I received a call from a complete stranger informing me of my mother’s ordeal. I had to rush back to Lagos the following day to bring Mama back home and get her bag from the taxi driver. My mother left for the village two days after and has since made it a point to call before she visits anyone.
