My parents had saved for years to buy a small house. My father invested a large portion of the down-payment in equities because he believed he could increase it before the purchase. Then the market environment turned brutal and panic took over. He sold several positions near the worst possible time.
We continued living in a rented house for another seven years. I was young, but I remember my mother never blaming him in front of us. Years later she told me they had nearly separated because of the secrecy around the losses. That period taught me that market losses are rarely just numbers on a screen.
