My Journey to Life Introduction
My Autobiography ââ¬Å"When my Parents First Metâ⬠Sometime in 1974 when Christmas is approaching, accordingly my parents told me that they happened to meet at a certain canteen in Green Hills San Juan, Rizal and came to know each other while they were still studying in College. Late after one year they came to be engaged with each other. Knowing more each family background, and accepted by both. After my father had graduated his course in Manila, they decided with both parental onsentââ¬â¢s to get marry. They went home to Batanes to receive their matrimony of marriage at the Miraculous Medal of Virgin Mary at Itbud, Uyugan, Batanes. In their continuous companionship, in the hardship of living, they were blessed with three children, all girls. They were Cheryl, Richel, and Louelle. Even in their hardship of bringing up my sisters, still they never quit seeking better information which is getting into college. They survived with the effort.My father and mother both graduated the course of Bachelor of Science in Commerce major in Accounting at Saint Dominic College, Basco, Batanes, sometime in 1990. For better qualification, they were both employed on level 2 ranked and file positions. My mother is still employed to the now Provincial Agriculturists Office as HRMO-II; and my father has just retired from the DPWH Batanes, their employment helps so much as the source to carry on in racing their first 3 children until they were in college. 6 years later blessed with another baby girl whom my father named Dandy. Dandy means according to him a child who hold up and down sweetly. After weeks, they brought their child to receive her baptism at Saint Dominic Paris Chapel. The child received her baptismal feminine name Dandelle which I am carrying on. I wrote this when I was still in Third Year High School for an Auto biography project. I only included the introduction part of it for my Autobiography is long and I don't want to tell much about me.
