Looking Forward

I have a hard time revisiting the past. On our recent vacation, we visited the area where we used to live, seeing a couple people from our past. But we intended to go see our old house, look up the neighbors, take some photos, but decided, when we were there, that we did not care about doing that.
I am weird in that I don't ever take pictures, or even think of taking a camera. I rarely, if ever, look at old photos or letters as I find it makes me uncomfortable to think about earlier times in my life. That is not to say they were not happy, with nice people and good memories, but I find that I am very focused in the present and looking forward. I was on the "not found" list for my 20th high school reunion (I found out later) and would not have gone if even if they had found me. I am also not very good at staying in touch with long-time friends, though I have been trying to be better about that since my breast cancer treatment ended.
Why am I writing this? Well, I have been thinking about the fact that I don't like looking back and wondering why that is. I thought if I wrote it down, it might help me figure it out.
