Who are you?

I was on my way to the pharmacy this morning and had some interesting thoughts. I started thinking about my cousin, Robyn. I used to be close to Robyn and her sister when we were kids. Even though we only saw each other about once a year, I always felt like we were close. I have not spoken of heard from her in five years. I sent her a birthday card about a year ago, and it was returned to sender. I have no idea where she lives, what she does for a living, or if she is in a relationship. It is so sad. We move on, we get involved with our own lives, and relatives get left behind. It is possible that I could never see her again. If I did see her, what would I say? I don't even know her now.
