@Cyracuz,
Thanks.
That one was fun. My niece in Maine made a FaceBook post last night simply saying she was "as happy as a clam".
I then said something silly like, "clams are restrained in their expression of feelings, however. They are actually shy and taciturn."
Something about that little dialogue tickled my fancy, however and I couldn't leave it at that. So I sat down and spent two or three hours playing around with the notion of clams' 'emotional life' and the end result was 'The Secret Life of Clams'.
(of course, I was undeterred by my almost total ignorance of clams except for eating them (many times) and digging them a few times. :-)
