q: when is the end of "spooky season?"
a: spooky season never ends because life, both the larger concept of existing as a conscious entity in an uncaring universe AND the fact that apparently clumps of matter in the right conditions will just fucking start moving around on their own, possibly as a result of the will of unseen parties who refuse to reveal themselves and explain their intentions, *never stops being utterly terrifying.*
the good news is, you can leave your Halloween decorations up until the heat death of the universe.
