Ouch! 18 months! Let's hope your shoulder gets better sooner.

Doesn't do much most of the time? When your tattoo does something what does it do? Something useful like cooking and cleaning? Sleeps for you so that you can load more energy from your tattoo if you some night couldn't get enough sleep?

My tattoo swears sometimes to strangers. Like if someone comes too close it swears few strong words and although it has a very low and strong voice I always get blamed for it's well selected words that I think should have been only whispered. Although necessary but still... one sometimes wants to behave.

The swearing, it didn't start right away, thanks for asking. I guess it started swearing about ten years ago when it no longer looked like a fearsome and angry dragon but more like a green ektoplazm ink stain.

The random needless wanted to do that. If I really had a say, the needless would go somewhere else than my fingers. Or perhaps that's also something that my dragonplazmstain tattoo does.
