I have asked myself the same question. To be honest I don't get it. I mean, are you going to tattoo your whole body with everyone that passes away that means something to you? That could be 10 people or more!
And on the other hand, was getting my tattoo silly and frivelous just because I got something fun that doesn't truly have a meaning behind it and I only got it for "decorative" purposes? I dunno. Good question cjcarter. :-)
