(urth) Memento Mori, Re: This Week in Google Alerts: conference, sketch

[Marc Aramini]

The stressful and long decline of rosemary is concerning. This might be the
most depressing analysis ever undertaken on urth list.  I have felt myself
to be very fortunate in my childhood heroes.  I am so grateful that my time
and Gene's just happened to overlap significantly.

There's a picture at the Fuller award I didn't know was taken at the time,
where, for the many kindnesses he showed me, thinking we were mostly
alone,  I told him that I loved him, and he would always be my hero,
thinking I would never see him again.  Then the nebulas were in California
the very next year, and Gene named grandmaster, so it proved to not be the
last time.
