Yeah, my wife will often respond with “I know you think I’m beautiful” which I think means the same thing. But that’s kinda the point - beauty isn’t objective. If someone can see you’re beautiful, that means you’re beautiful, because humans are the ones who made up the concept of beauty, so we get to decide what meets the “beautiful” cutoff. Now, yes, that means you can decide that you don’t meet the cutoff, but why do that?
