Read the passage given below and answer the question that follow : (129-135) My home town in the mid-1970s was laid-back place, resembling a remote rural area, except in having some amenities. Our house was almost at one end of the town. About 15 km away, there was a small village where a fair was held for a week every year during the harvest season. The village deity was worshipped by many from the places in the vicinity. Devotees thronged the fair not only for divine blessing but also for watching street-shows and other entertainment events. Only a mud track led to the village and everyone reached there by walking or on bullock carts. My father, an advocate by profession, was popular among the villagers. His clients from the place used to arrange bullock carts for us and a few family friends and relatives to attend the fair. The journey would start early in the morning. We children will be in a separate cart. I used to eagerly look forward to this occasion every year as though it was a journey of life-time and worth enjoying every minute of it. Money saved for this fair would be tucked firmly in my pockets during the journey. Whenever the cart jerked or sped away, I would hold my pockets tightly so that coins would not spill out. The crowd at the temple in the foothill used to be highly unorganised, especially the food counter where prasadam was served. Hot and spicy puffed rice and tea made of jaggery were the delectable. Going to the temple used to be the last priority of us children. Fearing elders' wrath, we would hurriedly finish the formality of darshan. Which one of the following statements is not true?
