Last week I went to my COS Conference.
Close of Service is the process in which you wrap up, close down, and get out of Dodge.
You evaluate and process the last 2 years.
You learn about all the forms and stuff you have to do before you leave.
Discussion is started and tips are given about how to deal with that place we left so long long ago.
One thing I leearned:
I'm a different person that when I left. Apparently I've changed. Apparently you've changed. We may not be friends anymore as we've drifted apart. It's sad I know. 
COS Conference was also to be the last time what remained of the 25 people I started out with would be together all in one place.
The first of us leaves in 3 days. I'm only a little bit jealous.
It is exciting and scary. There are things to do. There is also time to just take it all in, I think.
