A drop of ink can make a million think

First, you should know that yesterday I felt that I wanted to rant and just pure complain. I had a whole list of things that I could have gone off on.
Today, I feel "normal" or as close as I can come. But, yesterday's crap all started with one ditz too many.
I have a tattoo on my foot that reads "Nothing is Forever". I understand the irony that it provides, but also I got it for a reason. I got it after feeling down too many times thinking about my grandmother's death. To me, it represents the idea that pain and suffering in some one's life is not going to last, so stop fretting. After I got the tattoo my mother told me that while my grandma was going through her divorce, her Polish mother used to soothe her by saying "nothing is forever". I took this as a sign of a idea rightly done.
Although I like my tattoo, I have become increasingly more annoyed. I cannot begin to count the amount of times I have had some nit-wit approach me and say "hey, your tattoo is forever". In the beginning I laughed it off, but now I am at the point of saying, "In the long scheme of life, the tattoo is not forever, and I am not forever." I hate sounding pompous and wish I wouldn't have to bring up the life cycle to total strangers.
I think the only thing that makes me sad about my tattoo is that NOW I feel more at peace about my grandma's passing. I think that it would be great to have the tattoo go full circle and become something new. I think about getting it covered by something a little more uplifting. Also, humor is my middle name and nothing would be more funny than physically putting an expiration date on it. In the meantime, I'll proudly display it and will just have to say a prayer for the next dumb-ass that thinks before they speak. Amen.
