Yeah, eveyone always says things like that, like, 'When you're old and wrinkly that tatoo will look terrible'. But when I'm old and wrinkly I'll be far more concerned by my age and wrinkles than by any tatoos that may not look great. What differnce would it make?! You're not going to look a dream tatoo or not!
Equally, when I'm old and wrinkly I doubt that I'd mind much what the kids of the day were saying, I expect that they'll already be laughing at me about with my blue rinse, old woman flowery dresses and mad ramblings about 'in my day...' Why would I care about them laughing at a tatoo along with that?!
