Well Happy B'day, the world is better for you being here, D or not!
I too will be celebrating my first B'day w/ D at the end of this month. I probably won't be thinking much about it though. D is a minor thing in a sense compared to the other stuff I think about on a regular basis. He's just another person to take care of, but he also helps me take care of myself, which is a first for me! I welcome him to my B'day party (I don't know why he has taken on a male persona), and raise a toast in his honor!
