The Toy Story Conundrum says just because some scenario take place when you are not noticing, does not mean it does not happen at all, like the Toys being
alive cannot be disputed because they are
active when you
aren't watching.
Of course, there are other applications of the phrase too,
C : "I don't usually
kill spiders because they
kill the other insects. It's like they
work for me but I need them to stay in certain areas of the house."
A : "But why? they create invisible webs and are a pest, so I guess it's best to kill"
C : "I don't know if we do or if the spider gets them before I notice."
A: "Fair point, it's the toy story conundrum"
