This is an over-dramatization of a real life event.
Nobody ever tells you when your lips/tongue are blue. I mean, sure, sometimes you run into an awesome friend who always tells you when you look stupid... but most of the time that just doesn't happen. Instead you are left with a mouth full of blue (herpes) and a bucket full of embarrassment.
Having a blue/purple/green mouth isn't really something that will humiliate me to the point of breaking down into tears and running for the bathroom... but it's more about the principle of looking stupid without anybody saying anything to you. They just judge you internally.
You see, it's like there you are, walking down the hallway thinking you look all good looking and mysterious with your mysterious lollipop full of blue mystery flavors and deliciousness:
When suddenly you spot your reflection in something metallic and the entire picture you painted in your head about how you see yourself has shattered.
WHAT YOU THINK YOU LOOK LIKE:
WHAT YOU ACTUALLY LOOK LIKE:
The drastic switch from good-looking to monstrously hideous can throw your game off a bit if you don't see it coming.
I'm not saying that everyone can't pull off the "blue-lips" look, but in most cases it just makes you look like you are extremely cold and dying of hypothermia.
In any case, I think I'll stick to eating my blue candies at home, where
only my cats can judge me my cats will continue to shower me with unconditional love.
