This was wonderful to read. Welcome back; you were much missed.

I grok 'happy tears'. They happen when the Happy is so huge and great that it can't possibly be contained and spills out. Sometimes it's in the form of laughter and sometimes it's in the form of tears and sometimes it's both.

Someday, I should tell you about the 'chocolate bunny smile'. It's a concept better described in person, or I would tell it here.
