Because of how they’re packaged, there is no left and right twix. Left and right are relative terms. My left could be your right and someone else’s up or down. Before you open a package of twix each twix bar is in a superposition of left and right. They only gain cardinality when you tear open the packaging. Both sides of the packaging are designed to easily open so there is no objective top or bottom to the packaging.

Anon is crazy because he thinks that he can guess which twix is which as if being a left or right twix were an objective term. Sort of like if someone handed you two completely identical copies of a photograph and a marker and told you to highlight the differences, and then you found some differences.
