... and that's ok.
The committee quandry seems to be resolving itself.
X -- the chair -- is still doing impromptu meetings, and s/he seems to think that's sufficient. For example -- today -- Wednesday, s/he's scheduling a meeting for tomorrow.
I'm not available -- and I'm not willing to make myself available -- so, ok...
On the other hand, my new committee and I are getting along famously... and, we're actually doing something.
