exactly. I have about 20+ piercings & 5 tattoos, and while I got my piercings without thinking much about the consequences, tattoos are a lot different.
I edited my post, but yeah, you can be impulsive with piercings and easily go back to life without the piercing. With a tattoo, if you choose to laser it off it's expensive and very painful. If you keep it and hate it, at least it's a story you can tell to others that will make them think twice before acting so impulsively (I would hope.)
I have a tat I hate and have wanted to cover for a while, but I keep wondering if I'd end up hating the cover up. I do love how getting a tattoo feels tho. The pain is like pleasure for me.
