Ok, look. I realize I may be a party of one here, but let's discuss something.
That "you're beautiful" graffiti? You know how it's written on buildings and inside bathroom stalls? You know how people leave it, probably thinking they're leaving an uplifting message? You know how other people take pictures, re-blog it, pin it, and generally swoon over it?
Yeah, ok. Kudos for the thought and all.
But seriously? Seriously.
A) The way we use the world, "beauty" is almost always an external factor. We give lip service to internal beauty, but have you ever actually used that concept to describe someone? Really? We say people are kind, or smart, or brave, or adventurous, or any number of other positive things, but if we say they are beautiful, we mean that physically. If not, we have to clarify. "She's a really beautiful person. Inside and out." If you just leave it at "She's a really beautiful person," everyone will assume you mean physically. Which is fine. That's accurate for some people.
B) Beauty is not something to be proud of. You can be happy with it, for sure, but you did nothing to achieve your beauty. (Unless, I suppose, you did a ton of plastic surgery or have completely re-designed your face with make up, or whatever.) This is especially true in my case. I have some naturally lovely features, and some that are less so. There are parts of my body and face that I love the look of, and others that I don't. I'm not proud of my eyes. They are what they are. They're pretty, but I didn't do anything to make that happen. I'm not ashamed of my nose. It's not my favorite feature, but it isn't my fault. If you're going to give me a compliment, tell me something positive about myself that I actually have some control over. I can take pride in that.
C) A person's beauty (or lack thereof) is no where near the single most important thing about her. (And I say "her" because these standards are disproportionately applied to women and girls, though I recognize that men, boys, and people across the gender spectrum are also affected.)There is so. much. more. to a person than how he or she looks. Stop endowing this concept with more weight than it deserves.
And stop writing on stuff that you're not supposed to be writing on. Unless you're Banksy, keep your Sharpie in your pocket.
