Why wasn't I born with big beautiful eyes?

yes. you're still beautiful without big eyes.. you don't need the carbon copy celebrity look to clarify your beauty! everyone is meant to be different and you're look is what makes you amazing. i have medium eyes myself, trust me you aren't alone! and you said it yourself, since everyone else has big eyes, you're look makes you one-of-a-kind and that's what everyone wants to be. medium eyes are beautiful!
