tattoo

So last weekend I went to my parents house to print directions to a wedding. I was heading out of town and instead of back tracking and going home and losing about 45 mins I decided to hit the parents and use their printer.
Also I have been successfully hiding a rather large tattoo from them since last May. Its not that they don't know I have them, they have seen all the others (about 14) but it's just that I don't really want to disappoint them by continuing to get work that they disapprove. Plus its the same conversation about each one I get: "I really wish you wouldn't ruin your perfect body" or "only white trash has tattoos" or "you are much more classy than that, honey". I am classy and I am not white trash. The next day I was at my sisters house and my pop said that he noticed I had a new tattoo peeking out from my sweater the day before and asked to see it. I believe his comment was "oh lord that's huge". I felt awful in the pit of my stomach and I still am having trouble shaking it off. I personally don't want to stop getting tattoos and I believe they are beautiful on me and other people. I don't think that everyone should have them but I don't see why its such a big deal for my parents to just accept it. I am 32 years old and there is nothing else they don't like. In fact they are damn proud of me in most other aspects of my life. Why do I let it bother me so much?
