Never understood why people get tattoos and never will. I can't imagine being so confident about my love of a piece of art that I'd want to have it permanently inked on my skin for the rest of my life. All I could think about is "am I going to regret this in 10 years time?" -- and knowing me, I probably would 
I don't know. It's not just about the piece of art, but what it means to you, a specific moment in time. Rites. But then again, one shouldn't read too much into it either.
Obviously, if a kid has his favorite singer tattooed on his forehead when he's 15, he'll probably regret it sooner than later. Or if a tattoo is badly executed.
There's also the perception of "permanently" and "the rest of my life", and which can also contribute to one's aptitude to regret.
Me, I don't regret much ever and "the rest of my life" seems but a blink. I dare not use the word
permanently in the same sentence. If I ever had time for regrets, there would probably be more important things to worry about than my tattoos.
You know, I've waited quite a while before I got my first tattoo. And I think that me getting my first one coincides and/or marks the fact that I've started putting things into a different perpective and stopped thinking in terms of "permanent" and being so serious about everything. Learning to let go a bit and trusting my own judgement.
If I ever start worrying about my tattoos, I guess it'd be a sign that I have nothing serious to worry about. And since we're planning on having a kid, I'm sure I'll have plenty to worry about before I can ever sit and think about my tattoos. :P
They're just part of me, I don't think of them that much, but I still dig them when I see them. I've always loved bats and crows, so they were a safe bet I guess.
Obviously, that's
my take on it.
Understanding why people get tattoos doesn't mean you'd actually want one for yourself.
