i didn't. I believe i've now missed about 4. I went for several years after leaving, but i then started realizing that i was sending the wrong message by going.
When you are inactive and you go to the memorial, people look at you as a lazy incompetent, who is not strong enought to go to the meetings but somehow finds a way to crawl back to the memorial. I hated that i was now that person. I was the person who was not good enough for them, so i decided that i was going to play the role where they were not good enough for me to show up.
Best decision ever! Instead of a pathetic celebration, i had a nice dinner and watched some nice TV. I did reflect on how lucky i am that my eyes have been opened. I didn't have wine, but i had a nice cold beer instead. Even Jesus would be proud of that.
