I love your idea for your next tattoo...because I already have it! π
Please excuse the resolution. I'm a libra, which is an air sign, and my partner is a Virgo, which is an earth sign. From his point of view, he'll see the alchemical symbol of my sign and on my point of view, I'll see his. That's why I decided to have it on my ring finger. I know, too, cheesy. π I love your reason way better:
From my perspective looking down, I'll be looking at the earth - but for others seeing me, they will see air. This is my outward show, constantly seeking my earth.
