Everything’s relative. If you wore magnifying glasses (unless they were those annoying toy types that are all distorted) the increase in size would be to scale, so that it would seem like everyone’s bigger.
Except you, really, so it would probably impact the way you view the world, like you said.
Fevery thought (I’m home sick): Everyone has a different size magnifying glass in their eyes, and it should really be more powerful (and more humbling) as opposed to less powerful, where you feel bigger than everyone else. It’s a mindset thing.
