Haha. My mom got one tattoo back in the 90's...
It used to be years ago that sometimes people that didn't like tattoos would try to tell young people: 'Hey, whatever would your mom think if you got a tattoo!'
Whereas of course (at least in North America) women are now the majority of parlor clients (59%, apparently; some areas report 70%) and many young people have moms as well as dads that have gotten some ink.
Anyway, whatever people think, I reckon they can be an effective conversation-starter, with faith based designs.
