Pardon me, are you certain you are dealing with sane socks?
What are these “sane socks” of which you speak? Once they have traveled through the interdimensional portals in the washer and/or dryer, they’re never normal again.
That’s why you have to trick them into getting into the “sweater” bag. But they’re not only insane, but also not very bright, so after a few washings, getting into the bag is normal and natural to them... Most of them... Mostly...
