When my grandmother died, I was 1 year old. My father and my mother faced one of the worst crisis in their marriage (even with what happened after, like my family went bankrupt, I fought my father physically, my mother left home for days, my sister almost died, well, we had a rough story). They told me some tales of this time, and I'll tell them to you.
When my grandmother died, my mother lost all will to live. She cried everyday. She didn't even take care of her son, which is me, without crying. Most of the stories of me falling from beds, headfirst, or wrecking havoc are from this period. She woke up but was just... sad. She didn't do what she did before. She didn't work anymore. She only kept being numb.
This situation lasted for exactly a year. My mom tells me that, when she realized it was already a year her mother had died and she was still breathing, the world hadn't ended, some light started shining inside her again, and she got her will to live back.
It didn't happen when her father, the leader of the family, died, ten years before, blind and demented. It happened with her mother, a stay-at-home mom born in one of the poorest regions of my country at the time. If you don't know the relationship between someone and their parents, you can't judge what happened. Even when you know, the reaction may surprise you.
Respect Nverjos, we don't even know if this was the reason she stopped making the game. She might have died. She might have gotten a new job. We don't know. We don't even know her gender. We can only hope she returns and finishes this game with the same quality she showed us in the first and second runs.
