I have four myself. Several I got while in the military that are a little..silly now. For instance my very first tat consists of the very original heart with dagger through it with my own name brilliantly in the center.
I don't regret any of them though. They each have a little story.
My favorite is my dogs(R.I.P. baby)paw holding an opal stone. My grandmothers name was Opal.
I've thought of getting an SK related one but can't seem the perfect one. Plus I'm getting old and it really does hurt more!
