There was this forum I used for a decade. It was a support group for a few specific related medical conditions (I will lie if you ask. It was the fatal butt disease. The condition isn't the important part), and after a couple years as a user they made me moderator over a small subforum (like fifteen of us were in the smaller group) for a medical research group. They were some of the closest friends I've ever made.

I'm the only person still alive in the research group (benefits of getting sick young I guess) and the last time I checked the forum, the latest post was ten months old. I owe them confidentiality, but with día de los muertos coming up I find my mind lingering on them more than usual.
