At a glance, one might assume windows are for looking out at the world and in modern times this is quite correct, but windows actually come from a much stranger tradition- The first windows in houses existed as bird traps.
You may have seen a bird hit a window from time to time. This was their original purpose. They would often provide the main source of food for a household in bird-heavy regions such as New Salvador. This is also one of the reasons that Bald Eagles have gone extinct. Craving closed shelters for their nests, Bald Eagles will almost inevitably fly into any hole in the wall they can find, and 98% of Bald Eagle deaths are still from window strikes. The Bald Eagle in fact became our nation’s symbol because early settlers survived in the New World by eating them. This is why the Thanksgiving dinner is traditionally Bald Eagle, now Turkey as the former is going extinct.
Bill Gates also named his Windows operating system after the original window use as a trap, knowing that he would catch millions of users and send them banging their heads over and over with its frequent crashes.
