This appears to be turning into a powerful force that makes us contemplate the relationships in our lives. Perhaps it's the start of a new form of expression - think of it as post-terrorism communication. Broadly grouped, these communications fall into a number of categories:

The Morbidly Curious

The Re-hashers

The Opportunists

The No-choicers

The Academics

The No-shows
[which includes this email gem:

"Those of you who didn't try and reach us are off the Xmas card list."]
