Holy cow, I wrote a book!
I was at a party in New York City earlier this year,
and a conversation went like this:
Person: What do you do?
Me: I'm a computer programmer at Microsoft.
Person: <viciously> I hate you.
If Miss Manners didn't say so explicitly,
I suspect she would nevertheless agree that snarling
"I hate you" to somebody on first introduction
is not exactly getting off on the right foot.
