When you can see past all the huge negatives, and still care about that person and want to be there for them in whatever fashion you need to be, that is when love has conquered. Real love isn't loving their qualities, it's loving their flaws, as well.
I like the idea of a tree tattoo because I love trees but also as a memorial tattoo. Possibly having birds flying out of the tree representing loved ones that passed or having initials carved in the tree. I love the whole correlation between life and earth.
I want this along with the saying," The World is my country, all of mankind are my brethren and to do good is my religion."
