When I was born in Naples, Italy in 1953, that city was being bombed less than 10 years earlier during WWII.
My mom was homeless in Livorno, after she and her family were displaced because of bombing in Livorno which also destroyed their apartment building in 1943, ten years earlier.
The morning of the Cuban missal crisis in October of 1962, in Augusta, my dad was in the army and told us as we left for school that he might not be with us for a while as he might be deployed that day; my mom told us if we were attacked by Russia with the atom bomb, that we should come home immediately. She said that crying. It had only be 20 years earlier that she was living through the bombing of WWII and my father was in North Africa fighting in the same war.
In 1962, our family had been in the USA only six years and English as my second language had become my primary language and also for my older brother and sister.
When I graduated from high school in 1971, the Cuban missal crisis was nine years earlier, the pre-Vatican II Church was six years earlier.
When I entered the seminary in 1976, only twenty years earlier I was living in Naples, Italy where I was born and Italian was my first language and the New Roman Missal was only six years old and 12 years earlier it was the pre-Vatican II Church.
When I was ordained in 1980, the 1970 Roman Missal was only 10 years old.
Today, in the dying days of 2020, 1980 when I was ordained seems only a blink of an eye.
