It doesn't sound stupid at all. [In fact, it's exactly what Souji did for four years. Guess that's why he ended up dying, but uh....yeah.] It's terrifying, realizing the end is so near.

But we are all going to die sometime. Some of us are strangely and unfortunately blessed with knowing when it will come. I suppose that lets us try to make the most of the time we have left, though.
