Rest in peace

So, today, I received a terrible news that my teacher's spouse passed away. I won't disclose the name here. I really feel sorry for ..., but the only think I can do is wonder. I'm just curious as to how it happened, but some questions are best left unanswered, though, I'm still very eager to know the real truth behind the sudden passing. I plan to attend the funeral, just to pay my last respects. This just reminds me of my grandma. Death is something very unpredictable. But let's look at the bright side, without death, this whole world will be overcrowded, and everyone will be competing for food, resources and what not.
