Open For Piercings?

Open for piercings
Open for pain
And some people return there
Again and again

Myself, I don't get it
Like I don't get tattoos
A needle and ink
Is not something I'd choose

It's like, some folk are open
And tell you the lot,
While I like to hang on
To the secrets I've got

Perhaps I'm not open for business?
Perhaps I am a closed shop?
Or perhaps it's a case of
I know when to stop?
