Our neighbors never open their blinds. This morning, noticing it for the hundredth time, I wondered why. I know someone occupies that room and uses it during the day, so why do they not open the blinds? I do not understand indoorsy people. No judgement, just baffled - I really don't understand how to be satisfied with artificial light and small spaces. I'd feel trapped and be experiencing some major FOMO. 

Do you open the blinds? I get the occasional privacy reasoning, but if you don't open them otherwise, clue me in ... Help me understand ...why???!
