Every Iranian I've ever met is like this, it's annoying af. I've heard them say they invented drinking tea in the morning, that they are the only culture that enjoys eating the crispy rice at the bottom of the pot, how every popular saying is "Persian" (I heard an Iranian woman literally say "this might sound strange to you, but in my country we say that it's better to strike the iron while it's hot, heeeheee!"), all the grandma stuff with the plastic bags and the abuse (and they invented slippers too and Iranian grandmas discovered using a slipper to hit their children), and so many more normal and universal shit that it's unbelievable. I watch a lot of cooking videos on YouTube and every single time there's an Iranian in the comments asking why they didn't cook the depicted food in the Iranian way which is better and more authentic. They've really been brainwashed into thinking their culture is unique.
