two anxieties.

1. in my (forthcoming) thesis, i will have a theorem which is relevant to measurable co-tangent bundles on a certain class [1] of metric measure spaces.
   
   one requires two other theorems for this application. i've been working on writing a good proof of the first theorem, which reduces to a lemma.
   
   so far, the proof of the lemma takes 2 pages (standard amsart format) and i think when it's done, it will be 3 or more pages. possibly 4.
   
   i have a bad feeling about this.
   
   
   
2. i am ambivalent about this weekend. on one hand, i will see many friends and familiar faces. on the other hand, the reason is a tragic one.

[1] too technical to say, here; those of you who know me well will probably know the exact hypotheses.
