When you are trying to discourage your own teenage daughter to get inked up, when all of her role models are it's kind of tough. The only thing that'll stop her I feel is the cost of it, she's going to need save that money for university.
I've spent 1200 quid on tattoos in 3 years at uni. The cost will definitely not put her off.
