Woooooooh! That's extreme. Super extreme. I am curious to know what was the motivation for your parents to maintain that kind of a silence in the house. Honestly speaking, I am a lover of peace and silence. Too much noise causes me emotional and mental upheaval. Nonetheless, I never thought of a home this much quiet with that young a kid. It's baffling and interesting simultaneously.
Did you have siblings? It is said that When the siblings are together the only worrisome condition is the silence 😃. I tend to agree.
How about the time when there were some visitors at your home?
