I'm never wrong! haha!, lol, no seriously you make a valid point but tattoo's are a modular fashion item that you cannot remove.
My words were built on what I have been told by people with many tattoo's, a tattoo you get today is something you must come to terms with NOW that while it looks good and your happy with it TODAY you will not like it in 10 years time.
I agree with those sentiments.
Yes you can touch it up, yes you can try to make it look good, but the novelty will wear off and if you say that you can personilise a tattoo makes it good, no it doesn't it only makes it good if you in on the backstory.
You can tell a stranger the reason why you have a tattoo and they will go "oh wow, thats a cool story", but they wont go and tell anyone because its pointless in telling a story through someone else's tattoo.
