Backstory: I’ve always been interested in tattoos and started to seriously consider getting one early in college. I dallied about for a while, unsure of the image I would get. About three years ago I decided on the Celtic Cross knot. I have pondered it long and hard since then and finally feel that I am ready and certain that I want it permanently marked on my body. The specific design was done by my friend Sarah several months ago. This is the image.

I will be getting it on my right shoulder blade.
The obvious questions are: why are you getting a tattoo? And why are you getting this particular design?
Why a tattoo? Here are my thoughts. Tattoos are a way of decorating the body. Similar to other fashion choices such as piercings and nail polish, they enhance the beauty of the body. Because of their permanent nature, however, they are also symbolic and usually have a meaning specific to the person that chooses the tattoo. They can be a way of commemorating an event or expressing a thought or belief that the person sees as deeply meaningful to them. Artistically, they allow a person to treat themselves as art, their body as their canvas. A combination of taste and creativity lets them make themselves as interesting and beautiful as they can be.
I love the fact that tattoos are an expression of the individual, something unique to them. I think they can be beautiful (I think mine will be).
There definitely has been and to some extent perhaps still is a social stigma associated with tattoos. I do not see it as being significant enough to discourage me from getting mine. In my field I won’t suffer any sort of negative reaction; most of my friends and colleagues have more visible decorations than I ever plan to. If my life ends up somewhere else, the size and placement is discreet enough that no one will know I have it unless I want them to.
As to why I’ve chosen my design: I first discovered the Celtic Cross when I bought my necklace at the salt mine outside of Salzburg. I wore it every day for years, until the string started to wear out. The knot is a symbol of infinity: no beginning or end. Irish Christians used it as a symbol for the Trinity: the three points of the triangle representing the Father, Son, and Holy Spirit, the infinite nature representing the unity and infinity of God.
I love the idea of being marked with a representation of the Trinity, in a way reflecting my commitment to God, a commitment more permanent than my tattoo will ever be. The infinity of the knot sort of points to eternity and reminds me that I serve an infinite God and my soul will live forever. The Irish tradition reminds me that I come from Irish stock (as well as other stuff). The extra swirls added by Sarah complete the design aesthetically in a beautiful way and remind me of my friendship with her.
All of these reasons are long-lasting enough to make me comfortable with permanently marking this on my shoulder. I’m not going to outgrow my commitment to the Trinity, my eternity, or my heritage. The timing, me getting it next month, will commemorate my first year in New York. I will get it with Meg when she visits, which will also be a good bonding time for us.
Anyway, those are my thoughts. The reason I’m letting you all know about this before I get it done is because I expect that you may not be comfortable with the idea. I want to give you a chance to let me know any thoughts or concerns you may have. I really do want to hear from you--I can't promise to change my mind as a result of your comments, but I promise to seriously listen to and consider anything you have to say. I know this is a bit of a new thing for the family to handle, so please, anything you have to say, say it now.
