Haha, I love the 'H' idea!
I've already got several tattoos and I always think every tattoo tells a little bit about where you were in your life at that point in time. Regretting a tattoo would be regretting who you were, and therefore who you are now. In my opinion, anyway. Maybe that's a strange way of looking at it, but my tattoos are part of me, and I'd feel naked without them
