What is the significance of the many references to the domestic tranquility of the Frankenstein household?

The many references to the tranquility of the Frankenstein household foreshadows what will happen in the rest of the book. It's the calm before the storm. "I feel exquisite pleasure in dwelling on the recollections of childhood, before misfortune had tainted my mind, and changed its bright visions of extensive usefulness into gloomy and narrow reflections upon self (p. 20)." Everything Victor exprienced as a child, would eventually lead him to explore other realms of his environment. I believe Victor had too much time on his hands, which led him to learn things that maybe he shouldn't have.
