I have a tattoo of a moon and a star on my ankle. Not only does this have special symbolizm to me (Dione is the name of the moon goddess, mother of aphrodite and zeus, as well as a moon of saturn), but it is also the symbol of a very hard time in my life, and my strength to pull though out of it alive.

So while I agree, there are some tattoos that are obviously unneccesary (ie: drug related, pornographic), i think they do serve well purposes, like mine in reminding one of one's strength, or in being a symbol of one's faith/religion. basically, what it comes down to, is being a symbol, and i believe that if someone feels like they need something like that (forever) as a cornerstone/reminder, than who are you to judge?
