Recently me and my husband got in a huge fight because he was trying to demonstrate an example of the Hegelian concept of the "unity of opposites" (whatever that means) by claiming that the top and bottom bagels are opposite but also identical. I told him this is just wrong and that they are not "identical" in any meaningful sense (chirality is a basic concept in geometry/group theory). He kept stacking the bagels together and tried to show how they were "identical" and kept failing (because they're not) and then got angry and stormed out of the house. I haven't seen him since (this was about a day ago) and texted him and haven't heard back.
