I saw the conversation was about tattoos in another thread (Sub topic.) ...
So let's give it it's now thread!
FTR >>> I do not have a tattoo. And I am not sure what I would want if I were required to. But there are a few ground rules to it, if I had to get one:
#1 - No sayings in a language I am not fluent in, because I could never be sure of what was being said.
#2 - No names or likenesses of other people in my life, because people come and go ... even the ones who you think would never leave.
#3- And design must have a strong connection to who I am and what I believe in .. and whatever is related to it, must be from a long term association to my mind / thinking. i e ... if you haven't thought about it for years, the design could become a regret in a short amount of time thereafter.
#4 - Only to be applied by a professional at the craft who I can see previous results ... It's not like you can fix a bad tattoo or erase it if the "artist" is not competent.
#5 - Never in or on a part of the body where it can't be covered up, if desired or needed.
#6 - NOTHING OFFENSIVE to others. (That could be the majority of whatever you could dream up!)
#7 - Forget everything I have said ... I DON'T want to deface my body:-)
