Actually, we did. The family was together, and we ate, visited, cracked wise, same as always. The trappings were certainly different, but the core - the family - was still three, and, if anything, more in touch with the meaning of "giving thanks" than in quite a while.
It might well have been the most "adult" thanksgiving ever, because for once it was not about self-indulgence. This one was about being thankful & the joy that comes from being able to feel that feeling.
