That it's the same isn't a metaphor
How do I get you to see that it's the same? I smile, stand, sit etc literally as if you did it, my sex is literally the same as a cop's sexual laws, and my phone arranged in its apps is literally similar to your phone, that is a calligraphy app is the same for a person who writes calligraphy, and Sega games are the same for someone who's a big fan of the Sega Mega Drive.
I sit in a chair the way dad drives a car, I eat cheese salad all the same as dad, it's actually an old-fashioned 50s-type salad.
If almost everyone else is having jam on toast with a coffee at a café I do too, if almost everyone is associating hot chips with fish I do too, if almost every gardener wannabe who knows nothing about growing plants has an onion farming phone app I do too.
I'm literally the same, people noticed I have the same apps, that's what normal is, because normal means following norms, although it's complicated, I also follow principles and aren't odd or unusual, it's as simple as that but your finite quirky version of normal is simply what's emotionally sound and I doubt it's sane, people are crazy, that's you instead of following norms. I think weirdos twist the definition of normal to mean what they want it to mean, to the point that it's even in the dictionary, the first normals won't recognise you, nobody takes on board agreement to your version of normal, there are disagreements.
