There is a whole wide world beyond the little window, but it's too dark tonight. How do I know that there is something out there? What if there is absolutely nothing... or what if it's too much of everything? How would I find my way around that unknown? And do I want to venture out into the darkness? Maybe I should sit where I am, draped by my favorite curtains, finding meaning in the passing nature of life and beauty... in the safety of my room. Safe and sound.
But I'm not sure about the soundness.
